Bourns Rotary Optical Encoders

Bourns Optical Encoders provide a precise, non-contacting solution for sensing rotary position. These encoders utilize an optical disc and photodetector, and they generate a clean, square wave digital output signal for high-accuracy feedback. The optical encoders provide a long operational life and high-speed capabilities, making them ideal for demanding applications. These encoders provide a minimum insulation resistance of 1000MΩ at 500Vdc. These RoHS-compliant encoders are widely used in temperature control, speed control, and position sensing.
