Rotary encoders are electromechanical devices used for sensing in myriad applications — on motors paired with drives and automated machinery for everything from consumer electronics, elevators, and conveyor speed monitoring to position control on automated industrial machines and robotics. They track the turning of motor shafts to generate digital position and motion information. Whether incremental or absolute, magnetic or optical, rotary encoders track motor shaft rotation to generate digital position and motion information. Their use proliferates in industrial and commercial designs.

The application in which the motor encoder is being utilized will determine the motor encoder technology that needs to be used. The two broad types of motor encoder technologies available are:

Incremental Encoders: The output of an incremental motor encoder is used to control the speed of a motor shaft.
Absolute Encoders: The output of an absolute motor encoder indicates both the motion and the position of the motor shaft. Absolute motor encoders are most often used on Servo Motors in applications where position accuracy is required.
