Application: A digital encoder for measuring angular displacement. It offers strong resolution, high measurement accuracy, and reliable performance, making it a commonly used displacement sensor for measuring shaft rotation angle.

A code disc (grating disc) is a circular plate of a certain diameter with evenly spaced rectangular apertures. Since the photoelectric code disc is coaxial with the motor, when the motor rotates, the code disc (grating disc) rotates at the same speed as the motor. The detection device, composed of electronic components such as light-emitting diodes, detects and outputs several pulse signals. By calculating the number of pulses output by the photoelectric encoder per second, the current speed of the motor can be determined.
