Versatile rotary encoders, or shaft encoders, help you track the turning of motor shafts to generate digital position and motion information. For use as sensors on motors paired with drives and automated machinery, you’ll find encoders in everything from consumer electronics, elevators, and conveyor speed monitoring to position control on automated machines and robotics. Rotary encoders help provide information about position, velocity, and direction. Pulse generators can provide current sinking square-wave pulses with frequency proportional to the shaft rpm of monitored unit. See our assortment of rotary encoder accessories including brackets, clamps, couplings, flanges, measuring wheels, and shield cable. Choose many of the shaft encoders and accessories you need from Grainger.
