3.5 Input for external reference switch
If you are not using a reference switch:
• Seal the terminal with the protective cap supplied
(ISK-M8).
Selecting the reference switch:
• Use the correct switch type “normally-open contact” in
the PNP variant for the reference switch.
• Usea reference switch with screw locking (outer thread
M8x1) at the end of the cable or, as adapter, the connect-
ing cable KM8-M8-... with screw locking.
Use e. g. the following proximity switches from Festo:
– Magnetic proximity switches SMT-8M-...
– Inductive proximity sensor SIEN-...-M8B-...
• When selecting the sensor, note that the accuracy of the
switchover point of the sensor determines the accuracy of
the reference point.
