LED working indicator:
signal indicator, when sensing metal objects the light is on for normally open, the light is off for normally closed.
Difference between normally open (NO) and normally closed (NC):
Normally open (NO) is the usual state of the signal output line is disconnected state,
no signal output, when sensed to the object is closed, the output signal.

Normally closed (NC) is the usual state of the signal output line for the closed state, continuous signal output,
when the sense of the object is disconnected, close the signal.
