- Speed sensors are commonly included as an element in wheel bearing packages. Prior art sensors include passive sensors. Passive sensors provide a magnetic field with some type of magnet, generally combined in proximity with a sensing coil into a sensor component. The coil-magnet component is usually mounted fixed relative to the vehicle, since it has signal wires leaving it. A variable reluctance ring, generally a toothed iron ring, is mounted so as to turn at the speed of the wheel, within the magnetic field, thereby creating an electric signal that varies with wheel speed.

With regard to production of an integrated assembly, the prior sensors have presented some challenges. In particular, variable reluctance sensors include a large number of delicate parts that must be maintained in a connected state during packing in a housing. The fine wire coils and connections between components are particularly fragile.

The upper portion of the body portion can include a pair of retaining catches for retaining the pair of terminals. A capacitor can be electrically connected across the pair of terminals. The capacitor can be housed in a transverse slot located in the upper portion of the body, the transverse slot being located adjacent the pair of terminals.
