Standard Photoelectric Sensors
Circuit diagram
Output
When use is made of the PNP or NPN output circuit, the output circuit that is not selected is deactivated. When used as a comple-
mentary output, NPN or PNP outputs act in antiphase as the switch state changes.
Input
The sensor inputs are realised in positive logic and detect a positive voltage level of more than 1 ms duration as a valid signal if
the voltage level is between 10 V and the power supply voltage.
