Principle of encoder

Incremental rotary encoders provide a serial output signal on a single transmission line. One sensor must be connected to one controller.

An incremental encoder has at least 1 output signal “A” or typically 2 output signals, called “A” and “B”. These 2 signals are set up with a 90° offset, which is required for the detection of the encoder’s rotation. By turning the encoder clockwise, the “A” pulse is rising 90° ahead of the “B” pulse, by turning the shaft counterclockwise, the “B” pulse is rising ahead of the “A” pulse.


Additionally some incremental encoders output a “Z” signal. Once every rotation, this Z signal is rising for typically 90°, on the exact same position. This can be used as an accurate reference point.

Some incremental encoders also have additional differential signals, called “/A”, “/B” and “/Z”. These signals are inverted “A”, “B” and “Z” signals. Controllers can compare each pair (“A” must be equal to inverted “/A”) to ensure that there is no error during the transmission.

Additionally the transmission sensitivity is improved by transmitting the differential signals through a twisted pair cable.
