Npn proximity switch wiring diagram.

The box in the diagram represents the load. 1 5 khz ni brass pvc 26 awg 2. A common coloring convention for electronic proximity switches is brown for v power supply blue for ground pole of power supply and black for the switched output signal. Wiring diagrams show the hook up offour sensors with npn and pnp outputs.

I have managed to destroy a few sensors in the process. The black wire is the output load wire of the sensor. 3 wire and 4 wire dc inductive proximity sensors 3 wire and 4 wire dc 89 2 meter cable models dia. Mm model number range mm mounting electrical output switching frequency barrel material cable jacket size dwg.

3 wire and 4 wire dc. This means that multiple sensors can be connected to an input card with all sensor negative wires to one common wire. Proximity switch pnp type. Click on this link.

Either the load is connected to negative and the positive is switched pnp continue reading an easy way to remember pnp and npn sensor. In our case the plc input will be our load. Npn sensor outputs switch in a negative fashion. As you can see wiring a 3 wire sensor is not too difficult.

That is why we always have to refer to the manufactures wiring diagram. The common port of plc signal input and signal input can be taken as two ends of a load then the wire connection can be completed according to the wiring diagram of proximity sensor and the difference of npn proximity sensor and pnp proximity sensor. Just make sure the correct sensor part number is selected for the correct transistor circuit. Pnp n o pnp n c npn n o npn n c.

Proximity switch npn type. Here s a simple way remember how to wire up a 3 wire dc pnp or npn sensor. Two three or four wire proximity sensors contain a transistor oscillator and a. So there you have it.

This can be confusing at first when looking at the wiring diagrams. Some sensors have pnp and npn as well as no and nc output contacts. Pnp sensor outputs switch in a positive fashion. I get asked often on how to wire npn and pnp devices to the programmable logic controller.

Pnp switched positive npn switched negative switched refers to which side of the controlled load relay small indicator plc input is being switched electrically. Here s a quick way to wire npn and pnp devices. This wire is noted on the i o module s wiring diagram. 3 wire dc sensors can have a pnp sourcing or npn sinking output.
