Electrical Feedthroughs 

Introduction 

Standard electrical feedthroughs 

Electrical feedthroughs are components which enable the transfer of electrical power into or out of a hermetic chamber. Electrical feedthroughs 

consist of metal-ceramic-joints wheras the ceramic serves as an electrical insulator between the conductor and the connection 

flange. In addition to provide leak-tightness in high and ultra-high vacuum, many feedthroughs have to be resistant to high or cryogenic 

temperatures, high pressure and aggressive chemicals. We offer a wide range of feedthroughs for different operating conditions to meet 

the different demands of applications. We gladly help you with the choice of the suitable feedthrough. Please contact us. 

Important technical information 

The following technical facts and restrictions are to be considered when selecting the appropriate feedthrough: 

The so-called Paschen's Law describes the breakdown voltage (voltage at which electric flashovers between two electrodes with a 

fixed distance can occur) depending on the surrounding gas pressure. Knowing the operating pressure, this effect has to be considered 

when choosing a feedthrough to avoid short circuits and damages.The figure schematically shows the curve of the breakdown voltage 

depending on the surrounding pressure. 

All voltage ratings in this catalogue refer to a pressure of 1E-04 mbar or lower – an appropriate safety factor taken into account. The 

breakdown voltage is approx. 30 % of the given maximum voltage at atmosphere pressure. 

4 

Figure 1: Schematic chart of the breakdown voltage versus surrounding gas pressure. 

The voltage axis was normalized to the breakdown voltage at p = 1E-04 mbar. 

All electrical feedthroughs are 100 % leak tested and visually inspected during several quality control steps. The standard Helium leak 

rate specification is < 1E-09 mbar l/s. We also specify leak rates of < 1E-10 mbar l/s incl. leak test log upon request. 

The current ratings in this catalog section refer to the maximum current load per single conductor. These specifications are based on 

the current, which causes a maximum allowable temperature rise of 60 °C. 

Due to wide spread coefficients of thermal expansion of the materials involved in the electrical feedthroughs, the temperature gradient 

during any heating or cooling procedure should not exceed 25 °C per minute. 

The insulation resistance of ceramic materials decreases with increasing temperature. The insulation resistance at these temperatures 

may not be sufficient for some applications.

Introduction 

Feedthroughs, corresponding plug connectors and plugs are – if not explicitly stated otherwise – offered separately. 

Vacuum side plug connectors are usually made of PEEK (Polyether ether ketone). PEEK is a high temperature resistant polymer 

thermoplastic which has a comparatively low outgassing and high chemical resistance. PEEK plug connectors can be used in high 

vacuum down to p ~ 1E-09 mbar. For lower pressure applications (ultra high vacuum, UHV), fully metallic clamps or single contacts are 

the most widely used connector types. However, if you would like to use PEEK plug connectors in the UHV regime, we are pleased to 

advise you. 

Our standard flange material for feedthrough flanges is stainless steel 304 (1.4301). If you prefer a flange made of 316L (1.4404) or 

316LN-ESR (1.4429), please add in the order code "L" or "LNS" to the description of the flange (e.g. „CF16-…“ for stainless steel 304, 

„CF16L-…“ for stainless steel 316L, „CF16LNS-…“ for stainless steel 316LN-ESR). 

4 

Besides the mentioned standard feedthroughs, we offer all kinds of feedthroughs also on ISO-K and QCF flanges. Please add at the 

beginning of the order code the flange description "ISO...-" or "QCF...-" (e.g. "ISO63-..." for a flange DN63ISO-K). 

Special components 

Often, dimensions or specifications deviating from the standard are needed to realize a certain application, e. g. longer / shorter pins or 

non-magnetic materials. Modifications of standard feedthroughs like these can be realized in many cases. 

Additionally, we manufacture customized flanges with any combination of electrical feedthroughs and / or vacuum components, e. g. 

tubulated flanges, optical fiber feedthroughs, liquid feedthroughs, etc. in-house. 

If you do not find the suitable electrical feedthrough for your application, it might be possible to design and manufacture custom 

feedthroughs according to your special requirements. Please contact us, we gladly advise you.

Multipin Feedthroughs 

Introduction 

Multipin feedthroughs 

Multipin feedthroughs contain at least two conductors and they are designed to accept a plug connector on the air side. Some design 

variations allow for a vacuum side plug connector as well. The feedthroughs are ideally suited for a space-saving transmission of 

several electrical signals into vacuum. 

This section includes a wide range of circular multipin feedthroughs with up to 41 contacts for voltages from 500 V to 12 kV. Very 

commonly used, the oval-shaped SUB D feedthroughs provide 9 to 50 contacts in a small space. Micro D feedthroughs are very similar 

to SUB D feedthroughs, but with 9 to 51 contacts in an even smaller space they are more compact and provide a maximum space and 

weight saving. Additionally, VACOM offers compact power feedthroughs compatible with common Mini-Snap connectors. Brand new 

available are USB feedthroughs. 

Compact power feedthroughs with standard Mini-Snap connector 

4 

Compact power feedthroughs are available with 4 to 12 contacts and are characterized by small installation dimensions, full UHV 

compatibility and intermateability with plugs on both sides. Some versions can be charged with currents above 10 A per pin at voltages 

between 500 V and 1000 V. Compact power feedthroughs are especially used in cases where a small diameter of the feedthrough is of 

high importance. Additionally, for high vacuum applications or cases where welding is not an option also baseplate versions with O-ring 

sealing and solder cup contacts at the vacuum side are available. 

SUB D feedthroughs 

SUB D type feedthroughs provide a large number of contacts in confined space. The contacts are arranged according to MIL-C-24308. 

Air side and vacuum side plugs are available. 

Micro D feedthroughs 

Micro D feedthroughs are even more compact than SUB D feedthroughs. The contacts are arranged according to MIL-DTL-83513. The 

more compact design results in a reduction of the maximum voltage and current. The number of contacts varies between 9 and 51. 

Circular feedthroughs 

This subsection includes a wide range of feedthroughs with circular interfaces according to diverse standards for common circular plug 

connectors. Some versions can be used with air side and vacuum side plug. Also, versions for high voltage up to 12 kV or for high 

currents up to 46 A are available. 

USB feedthroughs 

USB feedthroughs are offered in two versions which differ in the vacuum side type of connection: a standard USB interface (USB, 

series A 2.0, male) or a non-standardized vacuum side interface for which we offer a vacuum compatible PEEK plug connector with 

crimp contacts. Both versions show a standard USB interface (USB, series A 2.0, male) on the air side for connecting a common USB 

cable.

Introduction 


Coaxial feedthroughs consist of two concentric conductor paths which are electrically isolated from each other by an alumina or glass 

ceramic insulator in between. The inner pin-shaped conductor serves as current carrying contact and is surrounded by a tubular 

outside conductor, which is usually at ground potential ("grounded shield"). The outer conductor shields the inner conductor from 

electromagnetic interference effects coming from outside. We also offer product variations with non-grounded ("floating") shield and / or 

matched impedance of 50 Ohm for several coaxial feedthroughs. Coaxial feedthroughs can be used universally and are particularly 

applied for transmitting high frequency signals up to 10 GHz and even beyond. 

4 

VACOM offers industry-standard coaxial feedthroughs including subminiature- (SMA), miniature- (BNC, MHV, SHV) and medium-size 

(N, HN) type. They cover a voltage range from 500 V up to 20 kV. Double ended versions and vacuum compatible plug connectors are 

available for most types. 

SMA (Subminiature Type A) 

feedthroughs offer a threaded interface in a subminiature size. Matched impedance designs are also available and are ideally suited for 

high frequency signal transmission above 10 GHz. Standard SMA feedthroughs are available as single or double ended units. 

Type N 

feedthroughs are the most frequently used medium-sized connectors for voltages up to 1.5 kV. The threaded coupling enables low 

noise and increased resistance to shock and vibration. Matched impedance designs are suitable for high frequency signal transmission 

above 6 GHz. Type N feedthroughs are available as single or double ended units. 

Type HN 

series feedthroughs comply with type N feedthroughs but have been designed for higher voltages (up to 7 kV). These designs with 

matched impedance are ideally suited for high frequency signal transmission or fast rise time pulses for data transmission. 

BNC 

feedthroughs are the most popular miniature connectors and can transmit voltages up to 500 V DC. BNC feedthroughs are equipped 

with quick connect / disconnect bayonet couplings. Matched impedance designs for the transmission of high frequency signals are also 

available. BNC feedthroughs are offered as single or double ended units with grounded or floating shield. 

MHV (Miniature High Voltage) 

feedthroughs - also characterized as high voltage BNC feedthroughs - are designed for high voltage applications of BNC feedthroughs 

between 500 V and 5 kV DC. MHV feedthroughs are also offered as single or double ended units with grounded or floating shield. 

SHV (Safe High Voltage) 

feedthroughs have a higher level of interface characteristics than MHV feedthroughs, including their individual identification. The outer 

contact ground connection is maintained through the center contact retaining ring. The center contact is recessed to prevent shock 

hazard during disconnection. Different designs are available for voltages from 5 kV to as 20 kV DC.

Introduction 


Feedthroughs in this section provide the transmission of high voltage and / or high current into a hermetic chamber throughout a wide 

range of applications.The designs vary considerably depending on their technical specifications and requirements. The air side ceramic 

surface is mostly covered with a high temperature glass coating in order to reduce surface contamination and to increase leakage 

current resistance. 

The maximum transferable voltage is 100 kV, maximum current is 800 A. On request, we also offer a liquid-cooled high power feedthrough 

capable of handling up to 1000 A. Liquid-cooled feedthroughs are typically used with grounded, closed cooling systems and 

non-conductive coolants such as deionized water or ethylene glycol.

Introduction 


are widely used for temperature measurements in vacuum applications, whereas the temperature is not measured directly but can 

be calculated from a thermoelectric voltage. The thermoelectric voltage is generated due to charge separation (EMF) caused by a 

temperature difference between the two ends of an electrical conductor. 

4 

The thermoelectric voltage (depending on the conductor material) is nearly proportional to the temperature gradient. Thermocouples 

consist of two different electrically conductive materials connected at one end. Using thermocouple feedthroughs the thermoelectric 

voltage (EMF) can be transmitted from inside of a chamber to an external indicating instrument. A high thermoelectric voltage, corrosion 

resistance and linearity are decisive factors for the selection of the material combination. Noble and base metals as well as alloys - 

adapted to different applications - are combined in thermocouples. Typical alloys are Alumel ® (nickel, aluminium and manganese), 

Chromel ® (nickel and chrome) and constantan (copper and nickel). 

Some thermocouple feedthrough types use compensating material ("compensating wire") instead of the actual thermocouple material. 

Compensating materials are characterized by thermoelectric properties ideally adapted to the corresponding thermocouple materials. 

For these types, we explicitly point out the use of compensating wire by footnotes ("Uses compensating wire"). Furthermore, it should 

be noted, that the temperature at junctions between a compensating wire and a true thermocouple conductor material must not exceed 

250 °C ("Max. junction temperature 250 °C"). 

Typical ANSI-standardized thermocouple material pairs are listed in the table below.

Isolators 

Introduction 

Isolators 

Electrical isolators consist of a non-conductive ceramic tube with a metal sleeve brazed at each end which can be welded to a standard 

vacuum flange. 

Isolators provide electrical isolation and ESD-protection of senstive system components installed at a vacuum chamber. They can also 

be used as a conduit to introduce cryogenic fluids, gases or water into hermetically sealed systems.

Introduction 

Accessories 

In this section you can find a wide range of accessories to our electrical feedthroughs, e. g. plug connectors for air and vacuum side, 

single crimp contacts (packed as set), vacuum compatible clamps and cables, stainless steel braided hoses, ceramic beads and 

ceramic spacers. 

Feedthroughs, corresponding plug connectors and plugs are – if not explicitly stated otherwise – offered separately. Plug connectors 

are always delivered including single contacts (for soldering or crimping). 

4 

Vacuum side plug connectors are usually made of PEEK (polyether ether ketone). PEEK is a high temperature resistant polymer 

thermoplastic with a comparatively low outgassing and high chemical resistance. PEEK plug connectors can be used in high vacuum to 

p ~ 1E-09 mbar. For lower pressure applications (ultra high vacuum, UHV), fully metallic clamps or single contacts are the most widely 

used connector types. However, if you would like to use PEEK plug connectors in the UHV regime, we are pleased to advise you.
