At present, the market of optical potentiometer products at home and abroad is blank, and the market is very broad. Optical potentiometer is the most suitable product for industrial production control equipment and has the most use value. If the optical potentiometer is adopted, similar faults will not occur within ten years, which is indeed guaranteed for production

The incremental rotary encoder converts the timing and phase relationship of its angle code disk through two internal photosensitive receivers to obtain the increase (positive direction) or decrease (negative direction) of the angle displacement of its angle code disk. After connecting the digital circuit, especially the single chip microcomputer, the incremental rotary encoder is more absolute in angle measurement and angular velocity measurement
