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 be connected to
– terminals A12, B12, GND for axis 1 and A22, B22, GND for axis 2
or
– tracks A, B and GND of the Mini-IO socket (X12 for axis 1, X22 for axis 2).
}
Track S (S12, S22) should be used to monitor the supply voltage (see drawing). A per-
mitted 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 long cable lengths. In this case we recommend that you
connect a resistor between the signal lines, as shown in the diagrams.
}
Connection of the proximity switches may only be performed in three-wire technology
and not in two-wire technology.
