This sensor is the ck1 00 2h capacitive proximity sensor. Heres a simple way remember how to wire up a 3 wire dc pnp or npn sensor.
Npn And Pnp Sensor Wiring To Plc
Pnp and npn sensor wiring diagram. Hence it is known as. The switching logic pnp or npn are not related to the supply voltage of the sensor or the operating voltage of the input. Wiring npn and pnp sensors into the plc with an interposing relay video click plc hmi rotary encoder dial input video. Npn switched negative switched refers to which side of the controlled load relay small indicator plc input is being switched electrically. Pnp switched positive. Two specific types of 3 wire sensors are available.
They are typically designed as three wire devices with leads or connections for. Wiring diagram for npn and pnp 4 wire sensors with t he d2 16nd3 2 technotes product group. Pnp versus npn switching. The fa q section may have information that can help. Connect sensor and input module to power. When connecting to the plc the plc input acts as the load.
A pnp sensor may be either no or nc as can an npn be either no or nc. Load could be lamp relay pneumatic valve plc input etc. Pnp sensor and its 3 wire diagram this sensor source its positive power to the output. Solid state devices are active as opposed to passive and therefore usually require some small amount of operating power. In contrast in north america the country where the transistor was invented relay outputs with potential free contacts for ac 110 v loads are most widely used. In my experience pnp switching outputs are used mainly in europe and npn outputs almost exclusively in asia.
Switched or sensor signal. Sensor output wires are run to separate plc inputs. It also mentions pnp 3 wire diagram and npn 3 wire diagram of these sensors. Sensor output wires are run to separate plc inputs. The figure 1 depicts 3 wire diagram of pnp sensor. The difference is a result of the internal circuit design and type of transistors used.
Sensor output wire is run straight to plc input. The 24 vdc and 0 vdc wires power the device. Here is a wiring diagram of a pnp sensor. The following is a wiring diagram of an open collector npn sensor. Hence it is known as sourcing sensor. Referring to the npn wiring diagram above note that the sensor supply voltage and the high side of the load are connected to the same point and are therefore at the same voltage.
The box in the diagram represents the load. Load refers to device to which the sensor delivers power. Sensor output wire is run straight to plc input. In our case the plc input will be our load. A key point to observe is that pnp and npn has nothing to do with whether the sensor is normally open no or normally closed nc ie. Pnp or npn style defines how the sensor operates the switched lead.
15 feb 2002 document name. 205 series information type. The v brown will be attached to the common input and the switching wire black will be attached to the input number. You will notice that the load appears between the v brown and switching wire black. Npn sensor and its 3 wire diagram this sensor sinks its ground to the output. 16 point dc input module last revised.
