This SN04-N NPN NO 5mm Distance Detector Proximity Sensor Switch Module will detect the presence of a metallic object within 4mm 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.
