Capacitive Proximity Sensors
-
I have read online that capacitive sensors can detect both metal and non-metal. Can anyone please explain me their working in simple terms? I read on various places online but information I found was too technical or less.
-
@davidward basically the sensor detects a change in the wave shape in front of it…
the wave shape is not magnetic, but different… (I can’t explain that part)

So they emit any kind of waves?
-
@davidward no, its the disruptive wave of their presence as compared the space without them… logically same as the magnetic wave detection…
wasn’t there before, now it is

Capacitive sensors use conduction plates that work like an open capacitor. Where you were reading online?

but those words don’t MEAN anything to me… not an electrical engineer
we were trying to find a laymans description

I got it. I was reading here https://www.derf.com/an-overview-on-proximity-sensors/ and question pop ups. Dust can be a bigger challenge to maintain sensors. How they can be protected? Does companies use any specific coating or something?
