What is the difference between a Hall effect transducer and a proximity sensor? It looks like one is general term and the other is a specific type.
I have a recipe for an anchor chain counter that calls for imbedding a magnet in the chain wheel and sensing it with a hall effect transducer with sourcing output. I have a selection of Omron proximity sensors with both sourcing and sinking outputs that can detect bolt heads and gear teeth and don't need the magnet. Can I safely assume that they can be substituted?
