Ø36mm incremental encoder

A36

Optical rotary encoder A36 is an incremental encoder that is available in digital or analog output signal versions depending on customer preferences. It can have up to 36.000 output pulses per revolution and, because of its quite small diameter, can be fitted in narrow areas.
