Re: PNP Inductive Sensor

I'd recommend NPN as well. Can the PNP switches run at 5V? if they only run at 12, you will need something to convert the 12V output down to 5. A resistor network or an op-amp could probably do it. If all else fails, you can run a small relay from the 12V that will trigger the 5V.
