The ELESTA GmbH develops and produces a modular, 3-channel, miniature optical encoder system
which may be of special interest for you as a manufacturer of complete rotary encoders.
This system is characterized by an extremely small installation volume and a very low power consumption of 4 - 6 mA.
This encoder system consists of a sensor with connector cable and a code wheel.
It can be easily integrated and the print design as well as the pin assignments can be customized.




* Incremental optical encoder; 
* Unique code wheel design; 
* High precision reflective system; 
* Low current consumption;
* Easy assembly;
* Very compact mounting form;
* High immunity to positional tolerance between code wheel and sensor;
