Standard/compact rotary encoders

Optically or magnetically scanning rotary encoders from TR-Electronic precisely detect positions in steel production, wind turbines, cranes and ships etc. and, when explosion protected, in painting plants. Miniature versions ensure the correct position in medical engineering and SIL3 approved absolute encoders provide for the necessary safety.

In addition to high-quality encoders for almost any application, we offer extensive accessories such as programming tools, displays and assembly components for quick and easy commissioning and seamless process integration.
