Abstract:
1. A gear tooth sensor assembly comprising: a housing; a first sensor module mounted to the housing and further comprising a first Hall effect sensor and a second Hall effect sensor spaced apart in a first plane and defining a first direction of spacing which lies in the first plane; a first plurality of leads extending from the first sensor module parallel to the first plane, each of the first plurality of leads being bent about an axis parallel to the first direction at a lead bend angle; a second sensor module mounted to the housing and further comprising a third Hall effect sensor and a fourth Hall effect sensor spaced apart in a second plane and defining a second direction of spacing which lies in the second plane; a second plurality of leads extending from the second sensor module parallel to the second plane, the second plurality of leads being bent about an axis parallel to the second direction at the lead bend angle; a circuit board lying in a single plane and mounted to the housing; wherein the housing positions the first sensor module and the second sensor module such that the first plane and the second plane intersect in a first angle and defines an intersecting line, and the first direction of spacing and the second direction of spacing each form a substantially identical second angle with the intersecting line; and wherein the circuit board is mounted to the housing at a third angle with respect to the intersecting line such that the first angle and the second angle are selected to be nonzero and the lead bend angle and the third angle are selected so that the first plurality of leads and the second plurality of leads extend perpendicularly toward the circuit board.
