In this video i demonstrate an npn inductive proximity sensor circuit. Classification by output circuit.
Using An Sn04 N Proximity Sensor As A Limit Switch
Npn proximity sensor wiring diagram. The box in the diagram represents the load. The following is a wiring diagram of an open collector npn sensor. Either the load is connected to negative and the positive is switched pnp continue reading an easy way to remember pnp and npn sensor. This classification is based on the type of output circuit and the output voltage. 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.
3 wire and 4 wire dc. Wiring diagrams show the hook up offour sensors with npn and pnp outputs. Here is a wiring diagram of an npn sensor. When an object is placed near the sensor the output device turns on. Pnp switched positive npn switched negative switched refers to which side of the controlled load relay small indicator plc input is being switched electrically. You will notice that the load appears between the v brown and switching wire black.
In our case the plc input will be our load. 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. Heres a simple way remember how to wire up a 3 wire dc pnp or npn sensor. When connecting to the plc the plc input acts as the load. This sensor is the ck1 00 2h capacitive proximity sensor.
