ABSTRACT:
A crankshaft position sensor having a reluctance sensing magnetic pickoff cooperating with sense features on a nearby, rotating sense wheel. The sense features are filled with a nonmagnetic electrically conductive material to enhance uniform eddy current flow within the sense wheel and where the magnetic pickup contains two coaxial magnetically polarized pole pieces.
