How It WorksInside the sensor, there is a coil that creates a magnetic field. When metal enters this field, it creates "eddy currents." Think of it like dropping a heavy coin into a pool of water; it causes a ripple. The sensor's circuit feels this change and triggers an electronic signal. Wiring ConnectionsThe sensor has three wires. It is critical to connect them correctly to prevent damage: 

• Brown wire: Connect to positive voltage (DC 6 - 36 V).
• Blue wire: Connect to ground (GND / 0 V).
• Black wire: This is your signal output.
