That's basically a crankshaft position sensor. I got the link from another guy asking if we could use it on a machine.
The gear pitch needed is .160 so at full quad the resolution should be .040 or about a mm. There is a data sheet link on the Allied Electronics page. The price I think was $27 via Allied but they had none in stock as it is a new product. Still, pretty cheap.
