I have one of these inductive sensors marked as
PL-08N which should work within a
4-30 VDC range and trigger at 8 mm or less. It's clearly a knockoff, meaning it has no manufacturer marking and all info is printed on a sticker.
I'm testing it's functionality so I tried to wire
12 V to brown,
GND to blue and I'm probing the black wire, but I'm experiencing a weird behaviour: the sensor properly triggers, but it doesn't recover, meaning the LED won't turn off moving the sensor away from the plate and the black wire doesn't go back to
What am I missing?
Looking for solutions I tried to run the device at
5 V (still within the declared range) expecting to have a very low sensitivity, just to discover:
- it activates at about 8 mm from the print bed (4 mm from my borosilicate glass)
- it properly recovers immediately after I move it away
I thought those devices had increased sensitivity with greater voltages...
