Fundamentals of Industrial Encoder Sensing
Technologies, Motion Detection Theory and
Methods, and Signal Output Styles

Encoders are used to determine the position, velocity and direction of a motor shaft or other mechanical motion. They provide information required for the precise control of a variety of applications, such as positioning a rotary table, pick and place, machine assembly, packaging, robotics and more. Regardless of type, all encoders provide a method of orientation detection that’s used as a reference point for position control.

An encoder (for industrial controls) is a special sensor that captures position
information and relays that data to other devices. The position information can be
determined using one of three technologies: optical encoder, magnetic encoder or capacitive encoder.
