FAQ
Question : What output do I need? NPN or PNP?
Answer: This is determined by the device you are connecting the sensor to. Most ADC
PLC modules (except 305 series) allow NPN or PNP sensors to b e connected.
Note:
Sinking = provides a path to supply common (–)
Sourcing = provides a path to supply source (+)
