Pnp sensor wiring diagram. Here is a wiring diagram of a pnp sensor. Examples used in this discussion are common setups in modern industry but vary depending on the. The following is a wiring diagram of an open collector npn sensor. The box in the diagram represents the load. Leakage current is a term indicating how much current might leak out on the switched lead even if the switch is off. Pnp switched positive npn switched negative switched refers to which side of the controlled load relay small indicator plc input is being switched electrically.
205 series information type. Many of these three wire sensors use standard m12 connectors and cordsets. Wiring diagram for npn and pnp 4 wire sensors with t he d2 16nd3 2 technotes product group. The v brown will be attached to the common input and the switching wire black will be attached to the input number. Heres a simple way remember how to wire up a 3 wire dc pnp or npn sensor. You will notice that the load appears between the v brown and switching wire black.
Sometimes more wires are included for extra functions but always review data sheets for the exact connections. 16 point dc input module last revised. This sensor is the ck1 00 2h capacitive proximity sensor. Three wire devices and leakage current. 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 fa q section may have information that can help.
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. 2 wire dc pnp 2 wire dc npn 3 wire dc pnp and 3 wire dc npn cases have been covered in this discussion. In our case the plc input will be our load. Npnpnp 4 wire sensorsvsd faq please refer to our tech support website for more info on sensors.
