3 Wire Proximity Sensor Wiring Diagram

Here s a simple way remember how to wire up a 3 wire dc pnp or npn sensor.

3 wire proximity sensor wiring diagram.

Current sourcing pnp outputs are internally connected to the power supply voltage and so should be wired externally to a load that has a connection to dc ground. In our case the plc input will be our load. 2 wire dc pnp 2 wire dc npn 3 wire dc pnp and 3 wire dc npn cases have been covered in this discussion. Connection diagrams for 3 or 4 wire sensors will also show the required wiring configuration for their type of output.

The box in the diagram represents the load. To read a wiring diagram first you need to know what basic elements are consisted of in a wiring diagram and also which photographic symbols are used to represent them. 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.

This sensor is the ck1 00 2h capacitive proximity sensor. Collection of 2 wire proximity sensor wiring diagram. 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. That is why we always have to refer to the manufactures wiring diagram.

Here is a wiring diagram of a pnp 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. Three wire sensor in plc three wire sensor connection in plc. 1 5 khz ni brass pvc 26 awg 2.

The typical elements in a wiring diagram are ground power supply wire and connection outcome gadgets switches resistors reasoning gate lights etc. It shows the components of the circuit as streamlined shapes and also the power as well as signal connections in between the devices. Examples used in this discussion are common setups in modern industry but vary depending on the. 3 wire and 4 wire dc inductive proximity sensors 3 wire and 4 wire dc 89 2 meter cable models dia.

12 nj2 12gm40 e2 2 flush pnp n o. A wiring diagram is a streamlined standard photographic depiction of an electrical circuit. 3 wire and 4 wire dc. 3 khz ss pur 22 awg 1 nbb2 12gm50 e0 2 flush npn n o.

Two three or four wire proximity sensors contain a transistor oscillator and a. Pnp switched positive npn switched negative switched refers to which side of the controlled load relay small indicator plc input is being switched electrically. Three wire sensors are used in various applications from detecting parts to locating position of the actual machine.
