Photoelectric encoder！

Photoelectric encoder photoelectric encoder supplier, by a mechanical displacement of the geometry of the photoelectric conversion output shaft into a pulse or digital sensors sensor suppliers. This is currently the most widely used sensors, photoelectric encoder encoder suppliers by the grating disc and the photodetector device component. Grating disk is partially a certain diameter circular plate, etc. opening of a number of rectangular holes. Since the photoelectric encoder coaxial with the motor, the motor is rotated, with the grating disk and the motor rotation speed, number of pulse signals output by the detection means detects the light emitting diode light emitting diode suppliers of electronic components, by calculating the second photoelectric encoder output the number of pulses will be able to reflect the current motor speed. In addition, to determine the direction of rotation encoder also provides a phase difference of 90 & ordm; the two pulse signals.
