  • The inductive proximity sensor uses the principle of electromagnetic radiation to detect or metallic objects.
  • These sensors can work even in wet environments without failing.
  • It creates an electromagnetic field when current is passed through it.
  • Metals unlike plastics are able to disrupt this field, giving us the ability to detect metals.
  • It can also be interfaced with microcontrollers such as the Arduino, ESP8266, ESP32 etc…

NB: It is most effective with ferrous metals



  • Supply voltage: 5-36V DC
