Cable for connection references -5 Data+ Positive, serial data output of differential linedriver. Connector Core colour Signals Description Pin 1 yellow Clock- Clock signal Data- Negative, serial data output of differential linedriver. Pin 2 green Clock+ Clock signal Clock+ Positive SSI clock input. Clock+ together with Clock- forms a current loop. A current of approx. 7 mA towards Clock+ input means logic 1 in positive logic. Pin 3 grey Data+ Data signal Pin 4 pink Data- Data signal Pin 5 blue Zero Zero setting input Pin 6 – n.c. – Pin 7 – n.c. – Pin 8 – n.c. – Pin 9 red d.u. do not use Pin 10 – n.c. – Pin 11 brown +Vs Supply voltage Pin 12 white 0V Supply voltage Rot. direction Input for setting a zero point anywhere within the encoder resolution. The zero setting operation is triggered by a Low impulse. Connect to +Vs after setting operation for maximum interference immunity. Impulse duration >2 ms.

Errors and omissions excepted. Zero Negative SSI clock input. Clock- together with Clock+ forms a current loop. A current of approx. 7 mA towards Clock- input means logic 0 in positive logic. 3 www.baumer.com/motion 13/8/2015 Clock- Encoder supply voltage.
