Description

When the metal approaches near-proximity switch sensing area, and Eady Current is induced in metal. Which in turn disturbs the magnetic field produced by the Inductive Proximity Sensor. This change is sensed by the sensor.

This inductive proximity switches can be non-contact, no pressure, no spark, quickly issued the electrical command. Accurately reflect the position and stroke movement mechanism. Positioning accuracy, operating frequency, service life. Easy to install and suitable for harsh environments.

This 8mm proximity sensor can detect a variety of metals, miniature size, long life, shielded type installation, anti-interference ability, 1mm detection distance, used for precise positioning of molds, precision machine tools, and robots.

Getting started with the Inductive Proximity Sensor Switch PNP DC 6V-36V

In this project you’re going to create a simple circuit with an Arduino and  Inductive proximity sensor that can detect target object. An LED will light up when object is detected.

Hardware required

  • Arduino Uno
  • Inductive proximity sensor
  • Jumper wires

 Connecting the Hardware

The metal proximity sensor will have three color wire. The blue should be in the ground, Black– Trigger Signal is on pin 2, brown is on +VCC which should be giving to Arduino + 5v VCC. Assemble all the parts by following the schematics below.

Upload the sample sketch

#define inductiveswitch 2 // Pin for Inductive proximity sensor

int ledPin = 13; // pin for the LED

void setup() {
Serial.begin(9600);
pinMode(ledPin, OUTPUT);
pinMode(inductiveswitch, INPUT);
}

void loop() {
int inductiveswitchValue = digitalRead(inductiveswitch);
if (inductiveswitchValue == HIGH){
digitalWrite(ledPin, HIGH);
Serial.println(“DETECTED”);
}
else{
digitalWrite(ledPin,LOW);
Serial.println(“NOT DETECTED”);
}
delay(1000);

}

Testing the circuit

In this example you need to open your serial monitor to see the incoming signal from the digital pin then make a threshold to determine if metal is detected or not.
