LJ12A3-4-Z / BX Proximity sensor N / O NPN 4mm

Description Attachments

This proximity sensor detects a metal object with a maximum distance of 4 mm from the sensor. The sensor works as an NPN transistor (normally open), which means that the voltage is cut off when a metal object is detected within 4 mm from the sensor. Pay attention! The sensor does not work on 5V.

The Netherlands
Does it work well, can sink enough current to ground (certainly more than 100 mA), must come really close to the metal for good detection, indeed according to specs best at 2 mm.

Does what it's supposed to do, even though it looks like the power and ground wires have been mixed up.

Works great Operates on 5 volts
Works on the 5 volts of my Raspberry Pi . I receive neat pulses from my water meter and the reading is high in Domoticz.
