Output signal EnDat 2.1

The EnDat protocol transfers digital data between an encoder and the evaluation electronics according to the RS485 specification. The absolute positions are transferred synchronously to the cycle signal (CLOCK ) specified by the evaluation electronics.

Output signal (SIN/COS track)

Signal sequence depicted for clockwise turning of the motor shaft with direction of view toward the A bearing side of the shaft.

2,5 V

The encoders are temperature-compensated and deliver standardized output signals.
