The brown pin is the positive voltage pin. Input voltage: 6V-36V.
The blue pin is the ground pin.
The black pin is the signal pin. When the proximity sensor doesn't detect any metal objects, this pin will be LOW, about 10 times less than the voltage that is fed to the positive voltage pin, the brown pin. For example, if you are feeding a voltage of 5V into the brown pin, when no metal objects are detected, the black pin will output about 0.5V or less.
