WHAT IS THE ABSOLUTE ENCODER CODE WHEEL?!

Changchun Rongde Optics Co.,Ltd.   Release time:2017/1/20   Browse:1015

In absolute encoders transparent segments alternate with opaque ones along several circular rings, according to a pattern that provides the position in a binary code configuration. To avoid encoding errors, a variant of the natural binary code is employed, the Gray code, which has the distinctive characteristic to vary only one binary digit between a code and the following one, ensuring a higher reliability both in code generation and decoding.
