What Are Encoders? Foundational Principles andTypes

An encoder is a sensing device that converts mechanical motion - rotation or linear displacement - into electrical signals. These signals are then interpreted by a controller (such as a PLC, VFD, or SCADA system) to determinate position, speed, direction, or expecreation. Encoder are classified by their sensing technology and out put type. The three primary technologies used in grid applications ar:
