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.

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