...NPN NO Proximity Sensor Strong Environmental Resistance Introduction Two specific types sensors are available; PNP and NPN. The difference is a result of the internal circuit design and type of transistors used. PNP and NPN has nothing to do with whether the sensor is normally open (N/O) or normally closed (N/C), i.e. a PNP sensor may be either N/O or N/C as can an NPN be either N/O or N/C. Why two types? The selection of a PNP
