An optical encoder is commonly housed within the motor assembly to achieve reliable and high positioning accuracy. The optical encoder system design is part of the motor’s design integration and manufacturing assembly. The optical encoder and code wheel are integrated into the motor during the motor assembly to form a closed-loop feedback system. The reporting output of the optical encoder is an absolute error under the excellent system design and well control of assembly on the optical encoder sensor position, rotation, and code wheel. Undoubtedly, an optical encoder can provide the highest accuracy in reporting the speed or position of the motor or linear stage as the superior position measurement.

An optical encoder is a rotary & linear motor feedback device for high-accuracy positioning across many industrial applications, such as industrial plotters, printers, housed encoders, servo motors, X-Y tables, AGV, robotic arms, turnstiles, etc.
