Inductive Proximity Sensor Detection Switch

• Inductive Proximity Sensor Detection Switch
• Detects metal objects within 4 mm of the sensor head
• Built-in red LED lights up
• Easy connection
• Output Signal: NPN
• Supply Voltage: 6 – 36 V DC

The Inductive Proximity Sensor Detection Switch accurately detects metal objects that are within 4 mm of the sensor head. When a metal object is detected, the built-in red LED lights up and the black signal wire is internally shorted to ground through an NPN transistor. When no object is detected, the signal is floating/high impedance.

Note: It is recommended to supply the sensor with no more than 6 V, and to put a series protection resistor between the signal output of the sensor and digital input of your board when connected to 5 V logic, such as Arduino compatible boards.
