Npn proximity switch

Most industrial proximity sensors (inductive, capacitive, ultrasonic and photo electric) are solid state. The term solid state refers to the type of components used within the sensor. Solid state electronic components such as transistors are used to switch the output of the sensor upon detection of an object. NPN -NC Proximity Sensors are available at Mouser Electronics.

This tech tip today shows how PNP and NPN wiring configurations are different.

The examples illustrated in the video are two different sensor diagrams.

In this video, I demonstrate an NPN inductive proximity sensor circuit.

When an object is placed near the sensor, the output device turns on. You can use an optocoupler as follows: schematic. Note: If the inductive Proximity sensor is wired incorrectly: The sensor LED will stay ON and go OFF when activated.

Normally Open sensor will work Normally Open). The sensors provide excellent even with difficult-to-detect objects, e. Thus, devices are available with N. NPN or PNP switching outputs, and cable or plug . This FAQ explains NPN and PNP transistors. NPN stands for negative, positive, negative. PNP stands for positive, negative.

I show you how to test and interface the sensor. NPN Proximity Sensor Output is normally HIGH when nothing is near it. More information can be obtained at our website. This includes all of the links mentioned in this video.

How to Build an NPN Inductive Proximity Sensor Circuit. In this project, we will show how to connect an inductive proximity sensor to an output. In this circuit, we will build an NPN inductive proximity sensor circuit.
