This set of two quadrature encoders for 20D extended-shaft motors provides precise rotational speed monitoring with 20 pulses per revolution of the motor shaft. The devices utilize a magnetic disc and Hall-effect sensors operating from 2.7-18V, and the digital outputs can be connected directly to a microcontroller. The encoders mount directly to the back of the motor, and the compact design and 6-pin JST PH connectors facilitate integration into robotic projects and control systems. Pololu 5660
