Advice on Proximity Sensors

[jehayes]

After reading all I can find on proximity sensors I have just one question: which one? Any advice on the correct model from the Factorymation catalog? NPN vs PNP? sensing distance? (I assume 4mm?) Thanks

Robert: Thanks, that is just right. Don't know how I missed it even after searching on "Factorymation."

You must have these threads memorized:)
