Product Description

An encoder is a sensor device that measures the position of rotating or linear motion and converts this position information into a digital signal that can be read and recognized by a computer or controller. The encoder and the motor are linked to read the position information fed back by the encoder to form an accurate and reliable closed-loop control system.
