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 $2

The resolution is determined by the number of teeth on the gear that is being sensed by the two Hall effect sensors in that integrated Honeywell sensor. For example, if you had a 100 tooth gear, you'd have 400 quadrature state changes per revolution. A spindle speed sensor doesn't really need
