Pnp Photoelectric Sensor Wiring Diagram

A sick wl12 3p2431 photo eye is an excellent example of a basic on off pnp sensor.

Pnp photoelectric sensor wiring diagram. The 0v blue will be attached to the common input and the switching wire black will be attached to the input number. Three wire sensors are used in various applications from detecting parts to locating position of the actual machine. It shows the parts of the circuit as streamlined forms and the power as well as signal links between the devices. A wiring diagram usually provides information concerning the family member setting and setup of devices and terminals on the tools to assist in building or servicing the device.

The sensor has two outputs that may be tied into a programmable logic controller input of the sinking type. Here s a simple way remember how to wire up a 3 wire dc pnp or npn sensor. A wiring diagram is a simplified traditional photographic representation of an electric circuit. Connect all 3 white wires from house from sensor and from light together.

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. When connecting to the plc the plc input acts as the 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. The following is a wiring diagram of an open collector pnp sensor.

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. 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. You will notice that the load appears between the 0v blue and switching wire black.

The wiring diagram dictates a standard configuration which requires a 24vdc and gnd signals for power. Connection diagrams for 3 or 4 wire sensors will also show the required wiring configuration for their type of output. Connect sensor s black wire to black wire coming from house.

Because npn sensors sink voltage and pnp sensors source voltage to the plc input npn and pnp sensors should never be mixed on a plc input card. Connect red sensor wire to light s black wire. Either the load is connected to negative and the positive is switched pnp continue reading an easy way to remember pnp and npn sensor. Examples used in this discussion are common setups in modern industry but vary depending on the.

Doing so can lead to an unsafe condition. Black wire is 120 volts so turn off switch or circuit breaker.
