Description:
This inductive proximity sensor will detect the prescence of a metallic object within 5mm of the surface of the sensor. The detection distance may vary slightly depending on the shape, size, and type of metal the object is made of. It can detect through thin, non-metallic materials and has an LED indicator that turns on when the device is powered, and increases in brightness when an object is detected.

This sensor is powered between 6 VDC and 36 VDC and works with any microcontroller and PhidgetInterfaceKit that has a digital input.

Specifications:

• Detects metallic objects
• Standard Detecting Distance: 5mm
