3.5 Input for external reference switch
If you are not using a reference switch:
• Seal the terminal with the supplied protective cap
(ISK-M8).
When selecting the reference switch:
• For the reference switch, use the correct “normally-open”
switch type in PNP configuration.
• Use a reference switch with screw-type lock (external
thread M8x1) at the cable end or – as adapter – the exten-
sion cable KM8-M8-... with screw-type lock.
• When selecting the sensor, note that the accuracy of the
switchover point of the sensor determines the accuracy of
the homing (reference) point.
Suitable proximity switches from Festo can be found in the
appendix A.2 “Accessories”.
