Function

The position transmitter detects the magnetic field of the piston magnet and con-
tinuously senses the piston movement in the sensing range. The position trans-
mitter can be operated in one of the following operating modes:

Proximity sensor with 2 programmable switching points (standard operation)

è

 4.2.1 Proximity Sensor Operating Mode.

Position transmitter with IO-Link communication

è

 4.2.2 Position Transmitter Operating Mode (IO-Link).

In the case of active IO-Link communication (IO-Link master required), the SDAS-
MHS switches automatically into the position transmitter operating mode.

4.2.1

Proximity Sensor Operating Mode

In the proximity sensor operating mode, 2 switching points can be programmed
within the sensing range.

Operation using capacitive operating key

Switching logic: normally open (NO)

Output signal 24 V DC (PNP or NPN)

Marking on the housing indicates the centre of the sensing range.
