This sensor is the ck1 00 2h capacitive proximity sensor. 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.
Interfacing An Inductive Proximity Sensor With A
Pnp and npn sensor wiring diagram. Connect sensor and input module to power. Pnp versus npn switching. The difference is a result of the internal circuit design and type of transistors used. Pnp switched positive. Pnp sensor and its 3 wire diagram this sensor source its positive power to the output. In our case the plc input will be our load.
The figure 1 depicts 3 wire diagram of pnp sensor. Switched or sensor signal. In my experience pnp switching outputs are used mainly in europe and npn outputs almost exclusively in asia. You will notice that the load appears between the v brown and switching wire black. The switching logic pnp or npn are not related to the supply voltage of the sensor or the operating voltage of the input. Sensor output wire is run straight to plc input.
Load refers to device to which the sensor delivers power. Hence it is known as. 205 series information type. Here is a wiring diagram of a pnp sensor. Heres a simple way remember how to wire up a 3 wire dc pnp or npn sensor. Sensor output wires are run to separate plc inputs.
Sensor output wires are run to separate plc inputs. Solid state devices are active as opposed to passive and therefore usually require some small amount of operating power. 15 feb 2002 document name. Npnpnp 4 wire sensorsvsd faq please refer to our tech support website for more info on sensors. The fa q section may have information that can help. They are typically designed as three wire devices with leads or connections for.
Load could be lamp relay pneumatic valve plc input etc. 16 point dc input module last revised. The following is a wiring diagram of an open collector npn 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. Pnp or npn style defines how the sensor operates the switched lead. Hence it is known as sourcing sensor.
It also mentions pnp 3 wire diagram and npn 3 wire diagram of these sensors. A pnp sensor may be either no or nc as can an npn be either no or nc. Two specific types of 3 wire sensors are available. The box in the diagram represents the 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. The 24 vdc and 0 vdc wires power the device.
The v brown will be attached to the common input and the switching wire black will be attached to the input number. When connecting to the plc the plc input acts as the load. Npn sensor and its 3 wire diagram this sensor sinks its ground to the output. Npn switched negative switched refers to which side of the controlled load relay small indicator plc input is being switched electrically. Wiring npn and pnp sensors into the plc with an interposing relay video click plc hmi rotary encoder dial input video. Wiring diagram for npn and pnp 4 wire sensors with t he d2 16nd3 2 technotes product group.
Sensor output wire is run straight to plc input.
