Help with SN04-N sensor
Posted: Sat Jan 09, 2021 10:58 pm
Hello,
I'm trying to install the SN04-N sensor, but there is very little information available online, I tried multiple wiring the sensor do light up with a close metallic object, but every time I try the Z axis will only go UP and won't go DOWN.
I did the wiring as advertise here (exect that i took the 12v from the FAN3 positive pin)

I also tried this wiring and every time the issues stay the same Z-axis goes only UP and not DOWN.

They add a resistance, but as the sensor power range is from 6V to 36V I don't see the need for that, am I wrong ?
Can anyone light me up please ?
Big thanks
