Optical Encoders

Industry Standard Optical Encoders for Sensing Speed and Direction


The Optical Encoders from CONTREX come in an industry standard cube style package that make it easy for direct replacement of other brand encoders.  Available in 600 pulses-per-revolution (PPR) and 1200 PPR, these encoders provide a single pulse-train for sensing motor speed, or quadrature pulse-trains for sensing speed and direction.

Speed Sensors

Sense Motor Shaft Speed and Direction for Closed-Loop Motion Control


CONTREX speed sensors can be used to sense the speed or speed and direction of a rotating motor shaft for closed-loop motion control applications.  Sensors are available in several different models including 2X Hall Effect, Quadrature, and Magnetic Pickup.  Though capable of working in nearly any installation, our speed sensors are specifically designed for easy drop-in installation with CONTREX Ring Kits.
