3.5 Input for external reference switch
If you are not using a reference switch:
• Seal the connection with the protective cap supplied
(ISK-M8).
When selecting the reference switch:
• For the reference switch, use the correct “N.O.”
(normally-open) switch type in PNP configuration.
• Use a reference switch with a screw-type lock (external
thread M8x1) at the end of the cable, or use the connect-
ing cable KM8-M8-... with a screw-type lock as an ad-
apter.
Use (e.g.) the following Festo proximity sensors:
– magnetic proximity sensor 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 homing (reference) point.
