2 models available.

Proximity switch 3 wire proximity sensor wiring diagram.

The box in the diagram represents the load. 24 v output 0 16 ma. 16 point dc input module. Some sensors have pnp and npn as well as no and nc output contacts.

Mm model number range mm mounting electrical output switching frequency barrel material cable jacket size dwg. 1 5 khz ni brass pvc 26 awg 2. Here is a wiring diagram of a pnp sensor. It shows the components of the circuit as streamlined shapes and also the power as well as signal connections in between the devices.

A wiring diagram is a streamlined standard photographic depiction of an electrical circuit. Collection of 2 wire proximity sensor wiring diagram. Input cards do not know the difference between 2 3 or 4 wire sensors but input cards for 2 wire sensors must be rated to accept the sensor s voltage drop and off state current level noted on datasheets sensors with 3 and 4 wires have dedicated output wires. The following schematic diagrams contrast the two modes of switch operation using red arrows to show the direction of current conventional flow notation.

Here s a simple way remember how to wire up a 3 wire dc pnp or npn sensor. Dual voltage. Normally open sensor will work normally open wiring diagram for npn and pnp 3 wire sensors with the dnd technotes product group. That is why we always have to refer to the manufactures wiring diagram.

24 48 v single 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. In both examples the load being driven by each proximity switch is a light emitting diode led. If the inductive proximity sensor is wired incorrectly.

In our case the plc input will be our load. Three wire sensors are used in various applications from detecting parts to locating position of the actual machine. 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. 3 wire and 4 wire dc inductive proximity sensors 3 wire and 4 wire dc 89 2 meter cable models dia.

Either the load is connected to negative and the positive is switched pnp continue reading an easy way to remember pnp and npn sensor. Wiring instructions for the micro switch vpx. Proximity switch consists a sensor circuit and a driver circuit. 12 nj2 12gm40 e2 2 flush pnp n o.

The sensor led will stay on and go off when activated. 2 wire proximity switch wiring diagram wiring diagram is a simplified standard pictorial representation of an electrical circuit it shows the components of the circuit as simplified shapes and the capacity and signal friends amid the devices. This sensor is the ck1 00 2h capacitive proximity sensor.
