Wire lenght Encoders

Wire draw encoders by TR-Electronic are equipped with absolute or incremental rotary encoders and fit the specific encoder series perfectly.

Three classes fulfill specific needs for different mechanical loads, duty cycle, lifetime, resolution resp. reproducibility


The SL 30 is designed for many years of use with a high activity rate. With a big number of options, the system can be adapted to many applications. Those wire draw mechanics are available as well approved for applications in explosive atmospheres, compatible with our AE _ 70.
