Three wire sensors are used in various applications from detecting parts to locating position of the actual machine.
Either the load is connected to negative and the positive is switched pnp continue reading an easy way to remember pnp and npn sensor.
Examples used in this discussion are common setups in modern industry but vary depending on the.
Here is a wiring diagram of a pnp sensor.

Pnp switched positive npn switched negative switched refers to which side of the controlled load relay small indicator plc input is being switched electrically.
They can come in all different technologies such as inductive photoelectric and capacitive just to list a few although the sensor technology may differ all 3 wire sensors are wired the same a three wire sensor has 3 wires present.

The box in the diagram represents the load.
That is why we always have to refer to the manufactures wiring diagram.

Connecting a 4 wire dc sensor is the same as a 3 wire sensor but each output wire is connected to a different input on the input card.
In our case the plc input will be our load.
2 wire dc pnp 2 wire dc npn 3 wire dc pnp and 3 wire dc npn cases have been covered in this discussion.
Some sensors have pnp and npn as well as no and nc output contacts.
This sensor is the ck1 00 2h capacitive proximity sensor.
