Incremental LYA010A  uses the principle of photoelectric conversion to directly output three sets of square wave pulses A, B, and Z phases; A. The phase difference between the B two sets of pulses is 90 degrees, making it easy to determine the direction of rotation, while the Z phase is one pulse per revolution, used for reference point positioning. Its LYA010A are simple principle construction, mechanical average lifespan of tens of thousands of hours or more, strong anti-interference ability, high reliability, and suitability for long-distance transmission. Its disadvantage is that it cannot output absolute position information of shaft LYA010A  .

Absolute encoder is a sensor that directly outputs digits. There are several concentric code disks along the radial direction on its circular code disk, and each channel is composed of transparent and opaque sector areas. The trees in adjacent code channels have a double relationship, and the number of code channels on the code disk is the number of bits of its binary digits. On one side of the LYA010A  disk is the light source, and on the other side, there is a photosensitive element corresponding to each code channel, When the disc is in different positions, each photosensitive element converts the corresponding level signal based on whether it is illuminated or not, forming a binary number. The characteristic of this encoder is that it does not require a counter and can read a fixed numerical code corresponding to the position at any position on the shaft. Obviously, the road must have N roads. At present, LYA010A  are 16 bit absolute encoder products in China.
