Smart encoders & actuators
Programmable draw-wire encoder,
a first for market!
Lika Electronic introduces a new range of incremental and absolute draw-wire encoders with increased
measuring lengths up to 5,000 mm (196.85”) and 10,000 mm (393.7”).
Worthy of remark the first cable-pulling measuring system with integral programmable incremental encoder.
Lika Electronic presents a new range of cable-pulling
measuring systems: under the spotlight in this month
SFE, the first wire-actuated measuring system in the
market with integral programmable incremental encoder;
and SFA, the absolute version encompassing a 25-
bit absolute encoder with SSI interface.
The cable-pulling mechanism has been redesigned and is now
able to reach increased measuring
lengths up to 5,000 mm (196.85”)
and 10,000 mm (393.7”).
Nevertheless the enclosure is very
compact and integral. Build with
premium-quality and rugged components,
draw-wire encoders are
ideally suited for use in typical industrial
applications (outriggers,
stabilizing slides, telescopic cranes,
booms in utility vehicles and mobile
equipment, forklifts, loading platforms
as well as electro-medical
equipment) and are aimed at reliable
operation in dynamic systems
with speeds up to 3 m/s (118 inches
per second). Installation is very simple
and fast, even in more constricted spaces, and ensures
perfect interchangeability with SF-I and SF-A series models.
SFE is the first wire-actuated measuring system in the market
with integral programmable incremental encoder,
thus it can be freely programmed via PC (linear resolution
up to 12 µm) to meet the more diverse individual requirements.
It provides AB0 and inverted /AB0 signals via Push-Pull
and Line Driver compatible universal output circuit.
The output signal voltage level is according to the input voltage
(+5Vdc +30Vdc). Furthermore SFE is also supplied with
preprogrammed resolution (500 to 50 µm).
SFA is a very simple and inexpensive
measuring system and provides
the absolute position information
via the robust and proven
SSI interface with Binary or Gray
output code. It is available in three
resolution versions: 25 µm, 50 µm
and 100 µm linear resolution. It is
further equipped with Zero setting
and Counting direction inputs.
Cable and M23 / M12 connector
options in either axial or radial
output are among the choice.
The range of draw-wire units from Lika Electronic will be
complemented with further models such as the CANopen
and EasyCAN fieldbus interface models. The new analogue
current and voltage version with travel length settable via
buttons will be brought out next June.
