Linear encoder 1.jpg
TR Electronic linear encoders acquire linear movements in machines, tools and installations according to your specific requirements with different technologies.
Linear technologies include Magnetostriction,
Glass scale transformation, Laser Distance Measurements, Barcode positioning systems and Wire Actuated, Draw Wire, Stringpot and Cable Pull Encoders.
TR Electronic Draw wire.jpg
TR Electronic Wire Actuated Encoders are available as complete units or as only the cable mechanism.
A range of different Wire Actuators, Stringpots, Cable Pull and Wire Draw encoders and units are available.

TR Electronic Heavy Duty Encoders

TR Electronic Absolute and Incremental Heavy Duty encoders are available in extremely robust housings,
made of aluminium or stainless steel,
and are equipped with heating or cooling if required.
Depending on the application the housings are even explosion-proof in accordance with ATEX, as well as salt and acid resistant.

TR Electronic Laser Distance Measurement

TR Electronic Laser Distance Measuring Systems are powerful optical sensors, which enable contactless measurement of long distances but fast enough for closed loop control. The measuring system comprises a laser light source, light collector, electronic evaluation and data interface as well as a reflector.
TR Electronic laser distance measuring systems enable absolute and wear-free measurement of long distances up to 240 metres, which can then be output via an SSI, field bus interface or Industrial Ethernet with a resolution up to of +/- 1mm with +/- 1mm repeatability.
