Npn proximity sensor wiring diagram. The v brown will be attached to the common input and the switching wire black will be attached to the input number. Industrial sensors of all types have connection diagrams. This classification is based on the type of output circuit and the output voltage. Pnp switched positive npn switched negative switched refers to which side of the controlled load relay small indicator plc input is being switched electrically. Wiring diagrams show the hook up offour sensors with npn and pnp outputs. 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 an object is placed near the sensor the output device turns on. 3 wire and 4 wire dc. When connecting to the plc the plc input acts as the load. Heres a simple way remember how to wire up a 3 wire dc pnp or npn sensor. You will notice that the load appears between the v brown and switching wire black. Here is a wiring diagram of an npn sensor.
In our case the plc input will be our load. Inductive proximity sensor cutaway with annotation. The following is a wiring diagram of an open collector npn sensor. This sensor is the ck1 00 2h capacitive proximity sensor. In this video i demonstrate an npn inductive proximity sensor circuit. Classification by output circuit.
