3.4.3 Wiring Example for Safety Sensor
If you want to wire a safety sensor you have to consider if you use the PNP and NPN type of
SF4C.
Wiring for PNP output
When using this device with PNP output, connect a PNP output type safety sensor. Connect the
emitter of the SF4C and the receiver of the safety sensor as follows.
In case of using lead wires other than those described below, perform wiring depending on your
application. For details on wiring, see "
Wiring" on page 34.
