Abstract
Two sensor modules that each contain two Hall effect sensors are positioned with respect to each other and with respect to a circuit board in a gear tooth sensor assembly. The sensor modules are arranged rotated in the plane of a positioning surface 120° with respect to each other, and tilted toward each other 15°. Sensor leads are bent at an angle of 98.64° such that the leads on both sensors pass perpendicularly through holes in a single circuit board tilted at an angle of 4.30° away from a plane tangent to the gear at a point halfway between the sensors. The sensor package is formed by a plastic mounting bracket arranged to position the sensor modules with respect to each other and the circuit board. The first two angles are selected, and the second two angles are determined so that the sensors are inserted perpendicular to the circuit board.
