When the metal gets into the sensor electromagnetic field, some changing signals are generated, and the metal detector can detect them. Then the metal detector can process the signals with electronic technology and drive theexecuting device (electromagnet and switches of motor) to remove the harmful metal. 
Timing function: Theelectric relay will be delayed released after actuation, and the time will be between 1~*0 seconds.
Output control: One pair of theconnection points of the electric relay are open, while the other pair areclosed.
