When interrogated, the encoder begins to transfer its gray or binary-code output, one bit per clock pulse, beginning with the most significant bit (MSB). When all bits have transferred, it resets ...

For each encoder position, there is a different binary output -- shaft position is absolutely determined. Tracks on absolute encoders often are arranged to produce a binary output called Gray code.

Typical outputs are 12 to 13 bits of BCD, gray, or natural binary code. The 13-bit outputs impose a lower frequency response (1200 rpm for 12 bits, versus 600 rpm for 13 bits) in exchange for the ...
