Proximity Switch Wiring Schematic

2 wire dc pnp 2 wire dc npn 3 wire dc pnp and 3 wire dc npn cases have been covered in this discussion.

Proximity switch wiring schematic. If the inductive proximity sensor is wired incorrectly. These inductive proximity sensors are available in ac dc and ac dc modes universal modes. The proximity sensor circuit wiring is done as shown in the below figure. Pnp switched positive npn switched negative switched refers to which side of the controlled load relay small indicator plc input is being switched electrically.

The sensor led will stay on and go off when activated. It shows the components of the circuit as streamlined shapes and also the power as well as signal connections in between the devices. Proximity switch consists a sensor circuit and a driver circuit. Proximity sensor circuit wiring.

Collection of 2 wire proximity sensor wiring diagram. The following schematic diagrams contrast the two modes of switch operation using red arrows to show the direction of current conventional flow notation. 16 point dc input module. In both examples the load being driven by each proximity switch is a light emitting diode led.

A wide range of metal objects may be used for the sensor including a metal plate a doorknob tin foil a set of burglar bars even a complete bicycle. A wiring diagram is a streamlined standard photographic depiction of an electrical circuit. 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. Not only this but any metal object which comes within range of the sensor itself becomes a sensor.

The proximity switch emits a loud falling siren when a body is detected within its range. Either the load is connected to negative and the positive is switched pnp continue reading an easy way to remember pnp and npn sensor. The operating range of the proximity sensor circuits is from 10v to 320v dc and 20v to 265v ac.
