Application

A digital encoder for measuring angular displacement. It offers strong resolution, high measurement accuracy, and reliable performance, making it one of the most commonly used displacement sensors for measuring shaft rotation angle.

The code disc (grating disc) has several rectangular holes evenly distributed on a circular plate of a certain diameter. Since the photoelectric code disc is coaxial with the motor, when the motor rotates, the code disc (grating disc) rotates at the same speed. 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 motor speed can be determined. (As shown below)
