LJ8A3-2-Z/DX Proximity Sensor Description
Proximity Sensors detect an object without touching it, and they, therefore, do not cause abrasion or damage to the object. Devices such as limit switches detect an object by contacting it, but Proximity Sensors are able to detect the presence of the object electrically, without having to touch it.
Three-wire proximity sensor wiring: the red (brown) wire is connected to the positive side of the power supply; the blue wire is connected to the 0V side of the power supply; the yellow (black) wire is the signal, which should be connected to the load.
