Proximity sensor

 Proximity sensor

Proximity sensor is basically used to indicate the presence of an object or how close it is.

Typically these types of sensors create an electromagnetic field or emit electromagnetic radiation and determine how close, far or what the nature of the object is from its change. Different types of proximity sensors are used to determine the nature of different types of objects, such as capacitive sensors. To identify plastic, wood or other conductive / conductive objects. Inductive sensors are used to detect metallic magnetic substances etc.

Introduction of sensor cable

three Proximity sensor (Proximity sensor) has three wires Black, Blue, Brown.

BK = Black is the output

BR = Brown is positive

BU = Blue is negative

There are two types of proximity sensors.

1. PNP

2. NPN

Switching of PNP SENSOR is from negative and switching of NPN SENSOR is from positive.
