Re: Interfacing with Allen-Bradley Sensors
Andy,
I attached a sketch of what should work. The NPN is a sinking device when it is made so I have added a pullup resistor. I have the signal going through an opto-isolator chip.

Opto-isolation is to keep the +12V for the prox isolated from the +5V.

Regards,
ChuckB
