Connection of proximity switches
The following proximity switch combinations can be connected:
} A: pnp, B: pnp
} A: npn, B: npn
} A: pnp, B: npn
} A: npn, B: pnp
When connecting proximity switches please note:
} Proximity switches can either be connected to terminals In1, In2 and GND or to tracks
A and B plus GND on the RJ45 socket.
} Track S should be used to monitor the supply voltage (see drawing). A permitted
voltage range can be entered in the menu.
} Connect the proximity switch to 24 VDC of the power supply.
} When connecting the proximity switches, please refer to the chapter entitled "EMC-
compliant wiring"
} Invalid signals may occur with cable lengths >50 m. In this case we recommend that
you connect a resistor between the signal lines, as shown in the diagrams.
