Npn proximity sensor wiring diagram. Heres a simple way remember how to wire up a 3 wire dc pnp or npn sensor. This classification is based on the type of output circuit and the output voltage. Here is a wiring diagram of an npn sensor. The v brown will be attached to the common input and the switching wire black will be attached to the input number. The box in the diagram represents the load. Pnp switched positive npn switched negative switched refers to which side of the controlled load relay small indicator plc input is being switched electrically.
In our case the plc input will be our load. Either the load is connected to negative and the positive is switched pnp continue reading an easy way to remember pnp and npn sensor. When connecting to the plc the plc input acts as the load. Inductive proximity sensor cutaway with annotation. Photoelectric sensor works on ir principle and this sensor has 4 wireno and nc in sensor has also been explained4 wire sensor has both no and nc operating mode in it. When an object is placed near the sensor the output device turns on.
3 wire and 4 wire dc. You will notice that the load appears between the v brown and switching wire black. Wiring diagrams show the hook up offour sensors with npn and pnp outputs. Industrial sensors of all types have connection diagrams. This sensor is the ck1 00 2h capacitive proximity sensor. In this video i demonstrate an npn inductive proximity sensor circuit.
