A wheel speed sensor includes an electromagnetic sensor having an electromagnetic sensor head disposed at a distal end thereof and a flange acting as a sensor support. The electromagnetic sensor head includes a magnet and an integrated circuit for sensing movement of a tone ring formed of magnetic attractive material. A sensor interface disposed at the distal end of the electromagnetic sensor is mechanically secured to a flange interface of the flange. The sensor interface can include outwardly projecting opposing tabs on opposing sides of the electromagnetic sensor head that are received by opposing apertures in parallel, spaced projecting arms that form the flange interface. In another arrangement, the sensor is inserted into an opening defined in the flange, and a retainer element is inserted into a slot formed on the electromagnetic sensor head such that the sensor cannot be extracted from the opening. The flanges are either annular and have an aperture for receiving a wheel shaft, or they have bushings for receiving a fastener to secure the wheel speed sensor to a vehicle. |
