3 Wire Ac Proximity Sensor Wiring Diagram

Pnp switched positive npn switched negative switched refers to which side of the controlled load relay small indicator plc input is being switched electrically.

3 wire ac proximity sensor wiring diagram.

Some sensors have pnp and npn as well as no and nc output contacts. 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. Here s a simple way remember how to wire up a 3 wire dc pnp or npn sensor.

Click on this link. That is why we always have to refer to the manufactures wiring diagram. Here is a wiring diagram of a pnp sensor. 2 wire dc pnp 2 wire dc npn 3 wire dc pnp and 3 wire dc npn cases have been covered in this discussion.

Mm model number range mm mounting electrical output switching frequency barrel material cable jacket size dwg. The box in the diagram represents the load. This sensor is the ck1 00 2h capacitive proximity sensor. 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.

Examples used in this discussion are common setups in modern industry but vary depending on the. 3 khz ss pur 22 awg 1 nbb2 12gm50 e0 2 flush npn n o. In our case the plc input will be our load. 3 wire and 4 wire dc inductive proximity sensors 3 wire and 4 wire dc 89 2 meter cable models dia.

1 5 khz ni brass pvc 26 awg 2. 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. 12 nj2 12gm40 e2 2 flush pnp n o.
