AND HIGHLIGHTS
JÜRGEN LAMPERT<br />
NEW CEO AT<br />
BÜRKLIN ELEKTRONIK<br />
DEAR<br />
READERS<br />
Just as we welcome you - dear customers and suppliers - here to our first <strong>Quarterly</strong> <strong>2022</strong>, we have to say goodbye<br />
at the same time. With effect from <strong>01</strong> February <strong>2022</strong>, we have handed over the sceptre to Jürgen Lampert. For the<br />
first time in the company‘s history, an external management team has taken the helm of the family business.<br />
Jürgen Lampert is an asset and an enrichment for the company in one! Due to his many years of experience at<br />
RS Components, he brings with him a strong understanding of the industry, international experience and the<br />
mentality that suits us. In addition, he comes at an important time for the company. The Corona pandemic has<br />
been overcome, at least economically, and <strong>Bürklin</strong> <strong>Elektronik</strong> is back on the road to success. Now it is time to set<br />
the strategically right course for future growth. And we are convinced that Jürgen Lampert is the right person<br />
here - you will certainly see as well as feel the positive effects of the change soon.<br />
Farewells like this always have a laughing and a crying eye. So, of course, we regret to leave the field operationally.<br />
Nevertheless, especially in our position, it is essential to take the best path for the company. Moreover, the change<br />
has no influence on the company structure - <strong>Bürklin</strong> <strong>Elektronik</strong> remains 100 % family-owned. We will continue to<br />
work closely with the new management.<br />
We would like to take this opportunity to thank you for the good cooperation over the past years, the good contacts<br />
as well as for your trust in us and our work - best thanks, stay healthy & of course enjoy this <strong>Quarterly</strong> #<strong>01</strong>/22!<br />
Your former management<br />
Johannes <strong>Bürklin</strong> & Veronika Tretter<br />
I would like to welcome you to our first <strong>Quarterly</strong> <strong>2022</strong> too.<br />
The global pandemic continues to affect all our personal and business lifes and I hope first and foremost that you<br />
and your families are well. All those affected by the virus have our sympathy and condolences and we wish from<br />
the bottom of our hearts: Get well soon!<br />
On 1 February, I took over the management of this traditional and successful company. The company‘s long tradition<br />
inspires me. I have known <strong>Bürklin</strong> <strong>Elektronik</strong> since the early days of my career in the distribution industry and look<br />
forward to continuing the successful history together with our customers, our suppliers and our employees.<br />
A very successful year 2021 for <strong>Bürklin</strong> <strong>Elektronik</strong> lies behind us and I am taking over a very healthy company.<br />
I am convinced that <strong>Bürklin</strong> <strong>Elektronik</strong> still has a lot of potential.<br />
For the future, I see various market trends that make me very optimistic:<br />
- The global demand for semiconductors will continue to grow exponentially - according to Tom Caulfield<br />
(CEO Globalfoundries) it will even double in the next 8-10 years.<br />
- The COVID 19 pandemic has shown the world how vulnerable international supply chains can be in the face<br />
of global shocks. This has triggered a political discussion about a possible shift of supply chains back to<br />
Germany and Europe. The aim is to reduce dependence on foreign suppliers and make the German economy<br />
more crisis-proof<br />
- The megatrend ‚digitalisation‘, which affects all areas of our lives, has gained even more momentum<br />
through the pandemic<br />
With 500.000+ articles from over 500 well-known manufacturers in our assortment, a highly motivated team<br />
coupled with our digital expertise, <strong>Bürklin</strong> <strong>Elektronik</strong>, as an independent German distributor in the heart of<br />
Europe, is ideally positioned for the future. We at <strong>Bürklin</strong> <strong>Elektronik</strong> will work together with our customers and<br />
our suppliers to further expand our strengths. I am looking forward to it.<br />
Enjoy reading and stay healthy.<br />
Best regards<br />
Jürgen Lampert<br />
CEO <strong>Bürklin</strong> <strong>Elektronik</strong><br />

PROJECT INSIGHTS<br />
SMART BÜRKLIN<br />
ONLINE SHOP<br />
TO INCREASE ITS DIGITAL PRESENCE, THE ONLINE SHARE OF SALES AND IMPORVE<br />
THE BUYING EXPERIENCE FOR ALL ITS CUSTOMERS, BÜRKLIN ELEKTRONIK CONTINUES<br />
TO INVEST IN A NEW, HIGH-PERFORMANCE ONLINE SHOP.<br />
Following our comprehensive articles<br />
on the „Smart <strong>Bürklin</strong> Online<br />
Shop“ project in the <strong>Bürklin</strong> <strong>Elektronik</strong><br />
<strong>Quarterly</strong>, we would also like<br />
to provide you with a transparent<br />
insight into current project events<br />
in the first quarter of <strong>2022</strong>.<br />
TECHNOLOGY CHANGE<br />
AND REALIGNMENT<br />
<strong>Bürklin</strong> <strong>Elektronik</strong> has decided<br />
to move away from a completely<br />
PWA-based online shop and to rely<br />
on a tried-and-tested front-end solution.<br />
Continuously emerging problems<br />
in the implementation of the<br />
PWA-technology and an associated<br />
project delay have made this decision<br />
necessary. With this realignment,<br />
<strong>Bürklin</strong> <strong>Elektronik</strong> will also deepen<br />
the cooperation with our already<br />
familiar partner Bits & Minds<br />
(<strong>Bürklin</strong> <strong>Elektronik</strong> <strong>Quarterly</strong><br />
#<strong>01</strong>/2021). Together with Bits &<br />
Minds, we can realize an anticipated<br />
Go-Live of the new online shop in<br />
the first half of <strong>2022</strong>.<br />
OUR CLAIM:<br />
WE WANT TO CONVINCE OUR<br />
CUSTOMERS & SUPPLIERS<br />
The satisfaction of our business<br />
partners and the fulfillment of our<br />
performance promises are our top<br />
priority. We pursue the claim to<br />
convince you - dear customers and<br />
suppliers - from day one that our<br />
online shop is customer-oriented<br />
and perfectly tailored to you. We<br />
work towards being able to fulfill this<br />
claim. Even if this means that we<br />
have had to realign the project and<br />
will therefore not be able to launch<br />
our new online shop in Q1/<strong>2022</strong> as<br />
planned.<br />
The implementation of our top<br />
project goals continues to demand<br />
precision and goal orientation from<br />
all project participants. The establishment<br />
of a future-proof interface<br />
is a crucial investment in the future<br />
and an important milestone in the<br />
future digitalization strategy of<br />
<strong>Bürklin</strong> <strong>Elektronik</strong>.<br />
We will keep you updated and let<br />
you know when our Smart <strong>Bürklin</strong><br />
Online Shop will be launched in the<br />
new design and with the promised<br />
added values (<strong>Bürklin</strong> <strong>Elektronik</strong><br />
<strong>Quarterly</strong> #02/2021) for all our<br />
customers and suppliers. We ourselves<br />
can hardly wait!<br />
Our current online shop is of course<br />
still available to you in full as usual -<br />
we look forward to your visit!<br />

CONVERSIONBOOSTING<br />
WITH A/B-TESTING &<br />
WEB ANALYTICS TO<br />
A USER-FRIENDLY<br />
ONLINE SHOP<br />
Customers of <strong>Bürklin</strong><br />
<strong>Elektronik</strong> have high<br />
expectations for the online<br />
shop. In addition to a good<br />
technical foundation, visitors<br />
expect a user-friendly<br />
online shop. They want<br />
to find the right products<br />
quickly and easily, have<br />
information about products<br />
clearly listed and complete<br />
the purchase quickly.<br />
Together with the<br />
eCommerce team of<br />
<strong>Bürklin</strong> <strong>Elektronik</strong>,<br />
Julian Kleinknecht and<br />
Nathalie Becker from<br />
ConversionBoosting<br />
created the foundations<br />
for a user-friendly online<br />
shop.<br />
By: JULIAN KLEINKNECHT<br />
CEO ConversionBoosting<br />
EARLY FEEDBACK ON<br />
CONCEPTION OF THE<br />
NEW ONLINE SHOP<br />
Even before programming<br />
began, the<br />
ConversionBoosting team<br />
analyzed all the important<br />
page types from the user‘s<br />
point of view. Above all, an<br />
experienced view from the<br />
outside helps to break out<br />
of the internal view and to<br />
question things.<br />
In addition to the expert<br />
analysis (based on the<br />
optimization of many other<br />
B2B online shops),<br />
ConversionBoosting<br />
worked with use cases.<br />
For each page type, it was<br />
defined which goal visitors<br />
pursue on the respective<br />
page. And then analyzed<br />
the pages accordingly and<br />
made optimization suggestions.<br />
PREPARATION FOR<br />
THE NEW ONLINE SHOP:<br />
A/B TESTS IN THE<br />
CURRENT ONLINE SHOP<br />
Making decisions based on<br />
past experiences with other<br />
shops works. However, the<br />
visitors and buyers as well<br />
as the purchasing situation<br />
are unique in every online<br />
shop.<br />
That‘s why A/B tests are the<br />
best tool of choice for making<br />
decisions. Visitors are<br />
randomly divided into two<br />
groups. One group is shown<br />
an alternative variant and<br />
after a defined period it is<br />
analyzed whether the<br />
change has led to the desired<br />
change (for example,<br />
more sales, lower bounce<br />
rate).<br />
All A/B tests were performed<br />
with Google<br />
Optimize, the free tool from<br />
Google. All tests were set<br />
up by ConversionBoosting<br />
„from the outside“ using<br />
JavaScript: JavaScript<br />
code is „put on top“ of the<br />
existing page. In this way,<br />
the test variant is created<br />
„on the fly“ for each visitor<br />
- and the developer resources<br />
are spared.<br />
Instead of conducting the<br />
A/B tests in the new online<br />
shop first, they were conducted<br />
in the current online<br />
shop - and the findings<br />
were applied to the conception<br />
of the new online shop.<br />

A/B TESTS WITHOUT<br />
INFLUENCE ARE ALSO<br />
POSITIVE<br />
Of course, not all A/B tests<br />
lead to the desired result.<br />
Some tests have no influence,<br />
others have a negative<br />
influence on relevant<br />
metrics.<br />
But even these seemingly<br />
bad tests are valuable.<br />
They show, for example,<br />
that there is no more<br />
optimization potential with<br />
a certain approach or on a<br />
certain page. You should<br />
invest your time and energy<br />
elsewhere.<br />
And if the change were<br />
to be rolled out without<br />
testing, it would result in a<br />
negative outcome and/or<br />
waste of resources.<br />
GOOGLE ANALYTICS:<br />
WHICH PAGES ARE<br />
REALLY IMPORTANT<br />
In addition to A/B testing<br />
and expert analysis, Google<br />
Analytics is an important<br />
conversion optimization<br />
tool. With the help of<br />
Google‘s powerful web analytics<br />
tool, you can understand<br />
visitors in detail.<br />
A fundamental question:<br />
Which page types and<br />
elements are actually<br />
used? Because that‘s the<br />
only place where it‘s worth<br />
investing time and budget.<br />
Projects are often started<br />
for elements that are not at<br />
all important for visitors.<br />
For <strong>Bürklin</strong> <strong>Elektronik</strong>, the<br />
search function, product<br />
lists and the product details<br />
page are particularly<br />
important. In contrast, the<br />
homepage is mainly used<br />
by existing customers (who<br />
are already convinced by<br />
<strong>Bürklin</strong> <strong>Elektronik</strong>) and<br />
then searched for directly.<br />
Elements such as teasers<br />
on the homepage are rarely<br />
used. It is not worth<br />
investing time here.<br />
GOOGLE ANALYTICS<br />
FOR THE NEW<br />
ONLINE SHOP<br />
The use of the new online<br />
shop should also be measured.<br />
Because you can<br />
only improve what you´re<br />
measuring.<br />
Based on a detailed<br />
plan for each page type,<br />
ConversionBoosting set<br />
up the measurement. This<br />
saved developer resources<br />
again. The measurement<br />
succeeded despite the<br />
great challenge of many<br />
products and therefore<br />
many different pages and<br />
page types.<br />

INGENIERBÜRO KOCH<br />
”FOR MORE THAN<br />
35 YEARS, WE HAVE FOUND<br />
IN BÜRKLIN ELEKTRONIK<br />
THE IDEAL COMPONENT AND<br />
TOOLING PARTNER FOR<br />
OUR TEST SYSTEMS“<br />
Special adapter for cells with<br />
160 mm length, 66 mm diameter<br />
and protruding threaded bolts<br />
This is complemented by expert<br />
advice and excellent service when<br />
there is a need for special solutions<br />
or special requirements. The most<br />
recent example - the removable pole<br />
terminal. While the pole terminal<br />
manufacturer attached great importance<br />
to the insulated head being<br />
captive and therefore flanged it on,<br />
this caused a great deal of additional<br />
work for the battery cell adapter;<br />
different cables would have been<br />
needed because the ring cable lugs<br />
supplied as standard on the cable<br />
sets of the battery testers could not<br />
be mounted on the pole sockets<br />
of the system. <strong>Bürklin</strong> <strong>Elektronik</strong><br />
consulted the manufacturer SKS/<br />
Hirschmann and within a few days<br />
the feedback was received that the<br />
terminals could also be manufactured<br />
and supplied with unscrewable<br />
heads.<br />
The problem was permanently<br />
solved - even for small quantities.<br />
Since then, Ingenieurbüro Koch has<br />
been purchasing custom-made pole<br />
sockets from <strong>Bürklin</strong> <strong>Elektronik</strong>.<br />
The only downer is somewhat longer<br />
delivery times, as the terminals are<br />
specially made in their own, admittedly<br />
small, batches.<br />
Every year, several hundred battery<br />
cell test adapters leave Koch‘s<br />
internal workshop in Unterschleissheim<br />
near Munich - and in similar<br />
other cases <strong>Bürklin</strong> <strong>Elektronik</strong> has<br />
repeatedly played a part in ensuring<br />
that the Koch brand promises of<br />
flexibility and robustness can be kept<br />
over the long term. - This is because<br />
the layout of the Koch systems and<br />
implementation are highly individual:<br />
The units are mounted on a plate<br />
in modules of up to ten adapters.<br />
In-house production with the help of<br />
a 3D-FDM printer developed by Koch<br />
for the special technical PC plastics<br />
required in this application means<br />
that special solutions, for example<br />
for special cell sizes, button cells<br />
or higher currents, can also be implemented<br />
without any problems.<br />
Ingenieurbüro Koch has specialised<br />
in testsystems since its foundation<br />
1986. Since then, founder Georg<br />
Koch has bought a large part of his<br />
tools and components from <strong>Bürklin</strong><br />
<strong>Elektronik</strong>.<br />
For more than ten years, battery cell<br />
test systems have made up the majority<br />
of the engineering company‘s<br />
portfolio. Initially, the company started<br />
with cylindrical cell adapters.<br />
In the meantime, Koch pouch cell<br />
adapter systems and modules are<br />
also used by a large number of<br />
well-known customers in battery<br />
production, assembly and electromobility.<br />
The graduate engineer<br />
has developed each of these individual<br />
and extremely high-quality<br />
and robust battery test equipments<br />
himself together with his son. The<br />
engineering company‘s portfolio is<br />
constantly adapting to the needs of<br />
the market.<br />
The decisive factor for Koch‘s cooperation<br />
with <strong>Bürklin</strong> <strong>Elektronik</strong> was<br />
the very large and complete range of<br />
products offered by the distributor<br />
<strong>Bürklin</strong> <strong>Elektronik</strong>, together with its<br />
rapid availability and consistently<br />
high quality from brand manufacturers.<br />
”Be it passive components,<br />
semiconductors, high-temperature-resistant<br />
stranded wires and<br />
cables, housings, plugs and sockets,<br />
binding posts and hand tools - pliers,<br />
soldering tools.... - almost everything<br />
is available in small quantities<br />
and extremely reliably on the next<br />
working day - this is important for us<br />
to be able to push our developments<br />
and react very individually to customer<br />
needs,“ says Koch.<br />
Special adapter for 4695 cell<br />
with contact on one side<br />
12 <strong>Bürklin</strong> <strong>Quarterly</strong><br />
www.buerklin.com<br />
13
The cells are contacted via<br />
spring-loaded contacts made of<br />
gold-plated berillyum copper. Due<br />
to the higher currents, the measurement<br />
is carried out via four instead<br />
of two test contacts per pole and one<br />
test contact sense in both systems.<br />
In contrast to the standard version<br />
of the previous round cell adapters,<br />
cells of 18 to 46 instead of 14 to 30<br />
mm diameter and 0-120 instead of<br />
30-80 mm length can now be tested.<br />
The connection to the test system is<br />
realised by means of pole terminals.<br />
The max. continuous current for the<br />
tests is 50 Amps, the max. current<br />
for up to ten minutes is 63 Amps.<br />
Alternatively, the connection to the<br />
test system can be made with safety<br />
laboratory sockets, as used in the<br />
standard solution for cells up to<br />
30 mm diameter and 80 mm length.<br />
The maximum current is then reduced<br />
to 32 A. Due to the modular<br />
design, it is possible to mechanically<br />
connect up to 10 measuring channels<br />
to one assembly, which leads<br />
to high stability when equipping<br />
the adapters. The maximum size of<br />
the pouch cells is currently 220 x<br />
270 mm, the maximum continuous<br />
current is 100 amperes. Larger cell<br />
dimensions and currents are possible<br />
on request.<br />
When asked about the special<br />
know-how required for the development<br />
and construction of the test<br />
adapters, the experienced developer<br />
with more than 30 years of professional<br />
experience in the battery<br />
environment emphasises a whole<br />
series of points: One is the experience<br />
with the test environments in<br />
which the adapters are used, which<br />
led to the modular design. The<br />
other is the 3D printing technology.<br />
This would not have been possible<br />
without the expertise from 3D model<br />
construction in free-form design<br />
of Christian Koch, the son of the<br />
adapter developer and also an<br />
engineer.<br />
In order to be able to achieve today‘s<br />
flexibility, there was a gradual<br />
changeover from milled to 3D-printed<br />
and laser-cut parts from 2<strong>01</strong>8<br />
onwards. The aim was to meet the<br />
high requirements for mechanical<br />
stability with simultaneous high<br />
thermal stress, which has now been<br />
achieved well with high-quality<br />
engineering plastics. However, a<br />
standard 3D printer was not capable<br />
of this. What is needed is a filament<br />
drying system for the filament with<br />
a diameter of 1.75 mm, a controlled<br />
heated printing chamber, a special<br />
material for the print bed, as well<br />
as a heating and cooling system for<br />
the print head, which has to melt the<br />
filament within a narrowly defined<br />
temperature zone with a difference<br />
of 200 degrees over a distance of<br />
15 mm. To achieve all this, a multitude<br />
of tests and optimisation steps<br />
were necessary.<br />

Electrically, too, extensive investigations<br />
of the current-carrying capacity<br />
were necessary to determine<br />
the optimum type and number of<br />
test needles and their arrangement.<br />
Optimising the current distribution<br />
between the test needles is at least<br />
as important. And the adapters also<br />
need good thermal management so<br />
that the test needles do not get too<br />
hot and, according to Koch, ”melt<br />
the plastic of the carrier from the<br />
inside“.<br />
In the case of pouch cells, there<br />
are a few more aspects to consider:<br />
different materials of the cells or<br />
arresters in pouch cells also require<br />
a great deal of attention and have<br />
an influence on the contacts and<br />
arrangement of the test specimens.<br />
- Are prismatic cells still missing?<br />
Here the mechanics are somewhat<br />
different and the cells are very large,<br />
the currents with up to 300/400 A<br />
very high. Of course, according to<br />
Georg and Christian Koch, it is<br />
also possible to build battery test<br />
adapters for this, but so far this has<br />
not been the focus of users. - At the<br />
moment, the focus is rather on the<br />
cell size: Just in time for the announcement<br />
by TESLA and other car<br />
manufacturers to immediately test<br />
larger round cells and presumably to<br />
use them in the future, Koch is offering<br />
the corresponding first highpower<br />
version of the round cell test<br />
adapters. With this, the announced<br />
new, large round cells with a length<br />
of up to 120 mm and a diameter of<br />
46 mm can also be tested safely and<br />
precisely, either individually or in<br />
parallel in the measuring cabinet.<br />
Where a large part of the tools and<br />
components come from is known.<br />

RAFI<br />
RETROFIT<br />
WITH KIS.ME<br />
EASY DIGITALISATION<br />
OF PROCESS FLOWS IN PRODUCTION<br />
AND INTRALOGISTICS.<br />
In many companies, despite a high level of automation<br />
and digitalisation, there are still unconnected work<br />
areas or processes that cannot provide centrally retrievable<br />
information. These typically include manual workplaces,<br />
remote delivery zones, waste collection locations<br />
and older machines without modern interfaces. Inadequate<br />
signalling options and missing connections to the<br />
control system not only cause unnecessary distances<br />
for internal material transport, but also make it difficult<br />
to determine key performance indicators. With KIS.ME,<br />
RAFI now provides a universal solution for the subsequent<br />
upgrade of production and intralogistics processes<br />
with a focus on flexibility, increased efficiency and<br />
simplicity.<br />
The KIS.ME system consists of the intelligent WLANcapable<br />
input units ”KIS.BOX“ with two illuminated<br />
pushbuttons, the RGB signal or machine lights<br />
”KIS.LIGHT“ as well as the web platform<br />
”KIS.MANAGER“, via which the devices<br />
are set up and individually configured<br />
for the respective application.<br />
THE NAME SAYS IT ALL<br />
The name KIS.ME is the acronym for ”Keep it simple,<br />
manage everything“ and describes both the underlying<br />
system concept from RAFI and the way it is used. ”With<br />
KIS.ME, we help companies in every industry to visualise<br />
and accelerate their analogue manufacturing and<br />
logistics processes with the simplest of means and to<br />
increase production efficiency,“ explains Maximilian<br />
Hämmerle, Project Manager at RAFI. ”All that is required<br />
is a power connection and WLAN at the point of use.“<br />
The decentrally placeable KIS.BOXes with M12 connection<br />
and integrated WLAN interface are used for on-site<br />
activation of messages. The input units have two buttons<br />
that can be individually configured and labelled, as well<br />
as two digital inputs and outputs for integrating light<br />
barriers, sensors or controllers, for example. Depending<br />
on the individual configuration, different actions can be<br />
triggered with them, such as the activation of remotely<br />
positioned KIS.LIGHTs in different colours, the sending of<br />
e-mails or the control of systems or application-specific<br />
actuators via relays.<br />
MASSIVE SIMPLIFICATIONS<br />
FOR INTERNAL LOGISTICS<br />
”The option to activate different pre-configured messages<br />
at the push of a button or signal input simplifies<br />
many procedures in previously non-digitalised processes<br />
considerably,“ explains Hämmerle. ”For example, where<br />
employees previously had to reach for the telephone or<br />
send e-mails for transport orders, a single press of the<br />
button is now sufficient with KIS.ME.”<br />

Starter Kit KIS.ME<br />
<strong>Bürklin</strong> no.: 12G1138<br />
The KIS.LIGHTs also offer completely new<br />
possibilities thanks to the WLAN interface and<br />
completely flexible placement, especially since<br />
they can signal different states, requirements<br />
or alarms in different colours with their RGB<br />
colour spectrum. Through signalling and signalling<br />
automatisms configured according<br />
to requirements, in-house logistics can be<br />
rationalised significantly in many cases.<br />
PLATFORM SOLUTION FOR<br />
SYSTEM MANAGEMENT AND<br />
PROCESS OPTIMISATION<br />
The heart of the KIS.ME system is<br />
the KIS.MANAGER for setting up,<br />
managing and monitoring the<br />
KIS.Devices. After account activation,<br />
the web platform provides all<br />
functions for clear display, automation and<br />
evaluation of the reporting processes. After onetime<br />
onboarding of the button boxes and signal lamps,<br />
any automatisms can be created on the platform with<br />
the help of a ”rule engine“. The easy-to-understand<br />
logic can be mastered without programming knowledge<br />
and makes it possible to record and trigger<br />
various actions and process operations with simple<br />
if-then-or rules. In addition to rule creation and administration,<br />
KIS.MANAGER can also be used to create<br />
different user roles with graduated rights. For example,<br />
an ”installer“ can set up new use cases and optimise<br />
existing processes, while an ”operator“ is not allowed to<br />
make any changes to the process. Another highlight of<br />
the platform is the central data storage of all events.<br />
By analysing and exporting data on all processes and<br />
states, trends, anomalies and special occurrences can<br />
be identified. Thus, the KIS.MANAGER not only serves<br />
as a platform for controlling and monitoring in real<br />
time, but also provides the data basis for continuous<br />
process optimisation.<br />
SIMPLE RETROFITTING IN ANY APPLICATION<br />
With KIS.ME, a wide variety of analogue processes can<br />
be digitally retrofitted in a simple way in order to obtain<br />
data where none was available before. KIS.MANAGER<br />
ensures a high level of transparency and supports users<br />
in identifying optimisation potential. The only requirements<br />
for the digital retrofit are a power supply (24V/<br />
DC or USB 5V/DC) and an internet connection via WLAN.<br />
A guest network without connection to the company<br />
or production network is also sufficient for this. The<br />
connection to existing machines and systems can be<br />
realised via external sensors that are simply retrofitted<br />
and connected directly to the KIS.Device. Alternatively,<br />
signals from the control systems can be tapped into<br />
existing signalling units.<br />
DEMAND-ORIENTED LICENSING<br />
RAFI offers the KIS.ME account with graduated licences<br />
and scopes of services. For those interested in trying<br />
out KIS.ME first, the manufacturer has issued a starter<br />
kit with which the entire system can be tested without<br />
obligation. The starter kit includes one KIS.BOX and one<br />
KIS.LIGHT, all necessary cables and a power bank to test<br />
the devices directly in the planned area of use without<br />
installation and assembly effort. All platform functions<br />
can be used for a free test period.<br />
More information on KIS.ME can be found on the website<br />
www.kisme.com as well as on LinkedIn and YouTube.<br />
The starter kit can also be requested there.<br />
TRANSPARENT DATA COLLECTION,<br />
EVALUATION AND PRESENTATION<br />
In order to maintain a transparent overview of the<br />
status of facilities and processes at all times, users can<br />
create individual dashboards with various widgets in<br />
KIS.MANAGER. Data records and KPIs (Key Performance<br />
Indicators) can be graphically prepared and displayed<br />
in a variety of ways. In addition, digital twins can be<br />
placed on the virtual shop floor with the help of uploaded<br />
building, warehouse or hall layout plans.<br />
If, for example, the status signal of a system sent to<br />
the signal light is simultaneously transmitted to a<br />
KIS.Device, the system status can also be monitored in<br />
KIS.MANAGER. ”Although KIS.ME unfolds its maximum<br />
benefit in production and logistics, the system is not<br />
limited to these application areas and industries. We<br />
have found that even employees whose companies have<br />
only been using KIS.ME for a short time come up with<br />
completely new ideas for use,“ says Hämmerle.<br />

TDK<br />
FERRITES WITH<br />
DISTRIBUTED AIR GAPS<br />
Ferrites are the first choice<br />
in the design of inductors<br />
for energy storage and<br />
transformers for energy<br />
transmission for power<br />
supplies. Increasing the efficiency<br />
plays an important<br />
role in the development of<br />
new designs.<br />
Air gaps in ferrites are<br />
a common method of<br />
delaying core saturation<br />
and thereby increasing the<br />
power density. However, an<br />
air gap creates a magnetic<br />
fringing flux that emits<br />
into the winding area and<br />
creates additional copper<br />
losses. The larger the air<br />
gap and the higher the<br />
frequency, the higher the<br />
copper losses. A certain<br />
part of the winding area<br />
cannot be used and this<br />
reduces the power density<br />
of the transformer.<br />
With the production<br />
technology of the distributed<br />
air gaps, TDK<br />
offers a solution to reduce<br />
the magnetic fringing flux<br />
and thereby to reduce the<br />
copper losses and the resulting<br />
heating and, on the<br />
other hand, to enlarge the<br />
effective winding window.<br />
Due to the even distribution of the air gaps (right), the magnetic<br />
leakage flux (red areas) can be significantly reduced<br />
compared to the solution with only one air gap (left). Solutions<br />
with three air gaps offer the best price / performance ratio<br />
when used in applications with high frequencies and reduce<br />
copper losses by up to 70 %.<br />
Ferrites with distributed<br />
air gaps increase the<br />
efficiency and improve<br />
the thermal behaviour of<br />
magnetic components.<br />
The use of ferrites with<br />
distributed air gaps<br />
reduces the magnetic<br />
fringing flux in the winding<br />
window by up to 70% and<br />
thereby reduces copper<br />
losses, electromagnetic<br />
interference and selfheating<br />
of the component.<br />
The result is a significantly<br />
higher power density, the<br />
use of a larger effective<br />
winding window and the<br />
possibility of downsizing.<br />
TDK‘s new standard range<br />
of ferrites with distributed<br />
air gaps offers the market<br />
easy and convenient access<br />
to what was once a highly<br />
customer-specialized technology.<br />
Available standard<br />
core designs are E, ETD<br />
and PQ cores, which are<br />
expanded to include ER,<br />
EQ and PM cores.<br />
Ferrites with distributed<br />
air gaps (Figure 2) can be<br />
used both in automotive<br />
electronics (e.g. on-board<br />
chargers and DC-DC converters)<br />
and in industrial<br />
applications, such as EV<br />
charging stations, solar<br />
inverters, uninterruptible<br />
power supplies (UPS),<br />
industrial switching mode<br />
power supplies and switching<br />
mode power supplies<br />
for telecommunications<br />
and server applications.<br />
ETD core with three distributed air gaps.<br />
The second and third gap is formed<br />
by the symmetrical counterpart.<br />

I-CON TRACE IOT<br />
SOLDERING STATION<br />
FINALLY COMPLETE HAND<br />
SOLDERING TRACEABILITY!<br />
With the i-CON TRACE, Ersa presents<br />
the world‘s first IoT soldering station<br />
that enables full traceability in manual<br />
soldering. Featuring integrated<br />
WLAN, Bluetooth and a network card<br />
on board, the i-CON TRACE provides<br />
100 % connectivity in digitally networked<br />
manufacturing processes<br />
straight out-of-the-box. This means<br />
that tasks that previously could only<br />
be reworked by machine can now<br />
be carried out by hand. Every single<br />
soldering process is recorded and<br />
documented electronically: PCB,<br />
component to be processed, soldering<br />
tip used, process temperature<br />
and soldering time.<br />
MAXIMUM CONNECTIVITY<br />
The software for operating the soldering<br />
station is available free of<br />
charge as a download and does not<br />
have to be installed on each individual<br />
PC as was previously the case.<br />
Instead, the i-CON Trace software<br />
is installed once on the customer‘s<br />
server. When a station has been<br />
integrated into the company network,<br />
all authorized terminals can access<br />
it via web browser. Specific soldering<br />
tasks can be assigned centrally to<br />
each soldering station - via MES, PC<br />
or mobile device. All essential parameters<br />
are preset centrally, so that<br />
process reliability is increased, and<br />
each workpiece is soldered exactly<br />
according to its specifications. The<br />
operator can fully concentrate on soldering,<br />
and the error rate is reduced.<br />
Device management also becomes<br />
much easier: firmware updates, calibration<br />
intervals, soldering tip wear -<br />
everything remains in focus thanks to<br />
connectivity and can be customized<br />
centrally.<br />
In addition, it is possible to connect<br />
i-CON TRACE with an existing<br />
MES so that soldering parameters<br />
used can be integrated and stored<br />
in complex networked production<br />
processes which already run via<br />
an MES. Already today, a recording<br />
of the entire soldering task can be<br />
downloaded in a specified file format<br />
and stored in a higher-level control<br />
system. Real-time communication<br />
between the soldering stations in the<br />
manufacturing area and the customer‘s<br />
MES is also possible through<br />
a gateway. A mobile app also allows<br />
the i-CON TRACE to be used like a<br />
conventional stand-alone soldering<br />
station without being connected to<br />
the company network.<br />
EASY OPERATION.<br />
GREEN MEANS GO!<br />
Featuring only an on/off switch and<br />
three LEDs, the operating concept<br />
differs significantly from other industrial<br />
soldering stations. The user<br />
starts by scanning the assembly, the<br />
soldering tip used, the solder wire<br />
and the flux. In this way, the system<br />
„knows“ that all requirements for<br />
the assigned soldering task have<br />
been met. The LED interface literally<br />
gives the user the green light as<br />
soon as the predefined temperature<br />
at the soldering tip is reached and<br />
the soldering process can be started.<br />
This ensures that each solder<br />
joint is soldered at exactly the right<br />
temperature and with the appropriate<br />
material. Any malfunctions (e.g.<br />
defective heating element, wrong<br />
soldering tip) are detected by the<br />
system and reported to the operator.<br />
Only when all parameters are correct<br />
can soldering be performed.<br />
STRONG PERFORMANCE AND<br />
EASY SOLDERING TIP CHANGE<br />
The i-CON TRACE impresses with<br />
maximum performance and minimum<br />
operating costs. Its 150-watt<br />
power ensures fast heat-up, even<br />
faster reheating and extremely<br />
precise temperature regulation.<br />
Proven technologies have been<br />
further developed - both the<br />
heating element and the soldering<br />
tip of the i-CON TRACE can still be<br />
changed individually without any loss<br />
of soldering performance. By changing<br />
the soldering tips separately<br />
from the heating element, each wear<br />
part only needs to be replaced when<br />
it is really necessary. The patented<br />
Tip‘n‘Turn concept of the i-CON<br />
TRACE soldering tips allows tips to<br />
be changed in record time and without<br />
the risk of burns. Each soldering<br />
tip has a bayonet lock which, in combination<br />
with the multifunctional tool<br />
holder, allows a quick, safe change.<br />
To do this, the soldering iron including<br />
tip only needs to be placed in one<br />
of the openings provided for this<br />
purpose and rotated by approx. 10°.<br />
In a nutshell: With the i-CON<br />
TRACE soldering station as the<br />
„missing link“, the gap in terms<br />
of Industry 4.0 and traceability in<br />
industrial electronics production is<br />
finally closed – in future, manual<br />
soldering processes can be tracked<br />
completely. The unique software<br />
concept and the intuitive and smart<br />
user interface make the manual<br />
soldering process safer than ever<br />
before.<br />
100 % connected: i-CON TRACE is the<br />
missing link between traceability and<br />
hand soldering in industrial electronics<br />
production. The latest Ersa soldering<br />
station convinces with a unique operating<br />
concept, outstanding performance and<br />
low running costs.<br />
<strong>Bürklin</strong> no.: 10L7100<br />
Ersa Tip´n´Turn enables tip change<br />
within record time. Each soldering tip<br />
has a bayonet lock providing for an<br />
especially quick and safe tip change -<br />
also when hot.<br />

TESTING ELECTROMOBILITY IN<br />
COMPLIANCE WITH STANDARDS<br />
Only with electromobility is it possible to achieve Germany‘s ambitious climate targets. From the customer‘s<br />
point of view, the attractiveness of electric vehicles depends primarily on how easy they are to use - especially<br />
when charging the battery. This is not just about the number and distribution of charging stations, but also about<br />
user-friendliness and safety for the user during the charging process. The testing of electrical safety as well as the<br />
functional tests must therefore take into account many different components involved in electromobility. During<br />
testing, the focus is on the safety of the testing person, electrician. Therefore, the correct selection of a suitable<br />
measuring / testing device is particularly important. These must comply with the relevant manufacturer and device<br />
standards. In particular, the individual test procedures should be standard-compliant. The relevant standard is<br />
DIN EN 61557 (VDE 0413) Electrical safety in low-voltage systems up to AC 1 000 V and DC 1 500 V - Equipment<br />
for testing, measuring or monitoring protective measures.<br />
TESTING CHARGING STATIONS<br />
A charging station is a device intended for charging<br />
electric vehicles equipment according to IEC 61851,<br />
which includes a plug device, a residual current device,<br />
a circuit breaker and a communication device. First,<br />
the qualified electrician performs a visual inspection for<br />
damage and defects and inspects the installation site.<br />
The subsequent electrical test includes, among other<br />
things measurements of leakage current, insulation<br />
resistance, grounding resistance and loop resistance.<br />
In addition, the residual current circuit breaker is checked.<br />
(according to DIN VDE <strong>01</strong>05-100). New technologies<br />
require new testing and measuring technology.<br />
In addition to AC charging points, DC fast charging<br />
points are now increasingly being installed. According<br />
to relevant standards, DC charging points should have<br />
special protective measures. DC charging points for<br />
electric vehicles with a permanently attached charging<br />
line should be equipped with a residual current device<br />
RCD on the line or in the power supply device.<br />
Further information on protective measures against<br />
residual currents in fixed installations can be found in<br />
IEC 60364-7-722.<br />
CHARGING STATION DIAGNOSTICS<br />
Checking the function of the charging station and communication<br />
with the vehicle is an important part of the<br />
measures to be carried out regularly to ensure the safe<br />
use of charging stations.<br />
For this purpose, various vehicle states are generated<br />
via external simulators. The charging process is simulated<br />
and various test runs are carried out. For this<br />
purpose, the vehicle connected to the column and the<br />
coding of the charging cables are simulated via adapters<br />
(according to VDE <strong>01</strong>22-1 / IEC 61851).<br />
- State A - no vehicle connected.<br />
- State B - vehicle connected but not ready for charging.<br />
- State C - vehicle connected and ready for loading,<br />
loading area ventilation not required.<br />
- State D - vehicle connected and ready for charging,<br />
charging area ventilation required, as well as<br />
- State E - error, short circuit CP-PE via internal diode.<br />
TESTING CHARGING CABLES<br />
At first glance, the variety of plugs and sockets at which<br />
an e-vehicle can be charged seems very confusing. In<br />
reality, the number of important connections for Europe<br />
can be reduced to two plugs. The most important and<br />
widespread AC charging connector in Germany and<br />
Europe is the Type 2 connector, which is supported by<br />
almost every modern electric vehicle or plug-in hybrid.<br />
For DC charging, the same applies to the CCS connector.<br />
Type 1 and CHAdeMO are the corresponding counterparts<br />
from Asia and North America and are primarily<br />
used in current vehicles. However, it can be assumed<br />
that the use will decrease constantly more and more in<br />
the future.<br />
tective conductor, the protective conductor resistance<br />
and the PRCD tripping current (according to VDE <strong>01</strong>22-1).<br />
The electrical test of the charging cable mode 3, to<br />
be carried out by means of a test adapter, includes, in<br />
addition to the visual inspection for damage, among<br />
other things, measurements of the protective conductor<br />
current, the insulation resistance, the protective conductor,<br />
the protective conductor resistance and the testing<br />
of the resistance coding for vehicle coupling and plug<br />
according to VDE <strong>01</strong>22-1.<br />
HIGH VOLTAGE TECHNOLOGY TESTING<br />
An important topic in electromobility is the diagnosis of<br />
safety and function on vehicles with electric or partially<br />
electric drive systems and the testing of high-voltage<br />
safety with compact precision measuring instruments.<br />
Energy storage with up to 500 V supply current highvoltage<br />
systems in hybrid and electric vehicles (passenger<br />
cars), but in the future the voltage level is expected<br />
to double. These voltages used in the systems require<br />
professional and regular inspection. After repair and<br />
overhaul, the vehicle systems must be tested by qualified<br />
persons using suitable measuring and testing technology.<br />
Via the CP (Control Pilot) data line, the charging station<br />
informs the electric car of the maximum charging<br />
current available. Via the PP contact (Plug Present/Proximity<br />
Pilot), both the charging station and the electric<br />
car can recognize how much load the connected charging<br />
cable may be subjected to.<br />
Both the high-voltage technology of electric vehicles,<br />
which can be tested with the multimeters of the Metrahit<br />
IM series, and all components of the charging infrastructure<br />
can be tested comprehensively and in compliance<br />
with standard-compliant testing with the test<br />
equipment of the Gossen Metrawatt brand.<br />
The electrical test of the charging cable Mode 2 is<br />
carried out using a test adapter in vehicle state C and<br />
includes, in addition to the visual inspection for damage,<br />
among other things measurements of the protective<br />
conductor current, the insulation resistance of the pro-<br />

ELECTROTHERMOGRAPHY –<br />
THERMAL IMAGER TESTO 883<br />
Thermal imaging camera<br />
testo 883<br />
<strong>Bürklin</strong> no.: 22K8596<br />
Electrothermography can prevent damage<br />
and avoid operational failures.<br />
At the same time, it requires expert<br />
knowledge. What must the thermal<br />
imaging camera and the thermographer<br />
be able to do? What advantages<br />
and possibilities does electrothermography<br />
offer and what sources<br />
of error lurk during recording and<br />
evaluation? Thermography, as an<br />
imaging measuring method, enables<br />
the non-contact visual measurement<br />
of surface temperatures on electrical<br />
installations. This allows thermal<br />
weak points to be localized and documented<br />
with a single image during<br />
operation, under real operating<br />
conditions and from a safe distance.<br />
This enables a quick early detection<br />
of problem zones and weak points,<br />
which minimizes the risk of fire and<br />
accidents and prevents consequential<br />
damage and production downtimes.<br />
