Linear displacement sensor

Incremental encoders directly use the principle of photoelectric conversion to output three sets of square wave pulses A, B and Z phase; A and B two sets of pulses have a phase difference of 90°, so that the direction of rotation can be easily judged, and the Z phase is per revolution One pulse is used for reference point positioning
