The working principle of absolute encoder！

Absolute value rotary encoder, because each location is absolutely unique, anti-interference, no power-down memory, has been increasingly widely used in various industrial systems, angle, length measurement and positioning control. Absolute encoders have a number of tracks on the encoder disc, each line in order to 2-line, 4 lines, 8 lines, 16 lines. . . . . . So that at each position of the encoder, by reading the pass and dark of each track, a set of binary zeros from 2 to 2 n-1 th power of binary binary coding, which Is called the n-bit absolute encoder. Such an encoder is determined by the mechanical position of the encoder disk and is not affected by power failure or interference. Absolute Encoder The uniqueness of each position determined by the mechanical position. It does not need to memorize. It does not need to find a reference point, and it does not always count, when it needs to know the position and when to read its position. In this way, the anti-jamming characteristics of the encoder, the reliability of the data is greatly enhanced.
