Output circuits
Figure 1 Push-pull output circuit (OUT1 at pin 4 / OUT2 at pin 2)
The sensor is factory set to a PNP output.
The output circuit is resistant to short-circuits and reversed power supply.
When use is made of the PNP or NPN output circuit, the output circuit that is
not selected is deactivated.
When used as a complementary output, NPN or PNP outputs act in antiphase
as the switch state changes.
