Photoelectric encoder, a photoelectric conversion to the output shaft of the mechanical geometry of displacement into a pulse or digital sensors. This currently the most widely used sensors, optical encoder is determined by the grating disk and photoelectric detection device component. Grating disc is a circular plate in such a diameter of several rectangular holes partially opened. Because coaxial photoelectric encoder and the motor, the motor rotates, the grating disk rotates with the same speed motor, the light-emitting diodes and other electronic components of the detection device detects certain pulse signal output
