WebMar 15, 2024 · What is a NPN Transistor. An NPN transistor is the most commonly used bipolar junction transistor, and is constructed by sandwiching a P-type semiconductor between two N-type semiconductors. An NPN transistor has three terminals– a collector, emitter and base. The NPN transistor behaves like two PN junctions diodes connected … WebFeb 10, 2024 · When used in a traditional relay type control circuit, it is normally possible to use either the PNP or the NPN type of sensor as shown below. PNP sensors tend to be more commonly used. Wiring Traditional relay type control circuit; Use with a programmable logic controller (PLC). When selecting a sensor to be used with a PLC, it is very ...
