Abstract
A speed sensor for sensing rotating speed of a wheel having projections. An elongated tubular sensor body connects to a flange, the flange being adapted from mounting in a housing wall in proximity to the wheel. A Hall-Effect sensor is provided within the sensor body and circuitry is also located there for processing signals from the Hall-Effect sensor. The Hall-Effect sensor is positioned for sensing the projections of the wheel through a portion of a peripheral sidewall of the cylindrical sensor body so that the Hall-Effect sensor is 'side-looking'. An alignment mark is employed to position the Hall-Effect sensor in sensing alignment with the wheel. A diameter of the flange cooperates with a placement of a receiving aperture in the housing for setting a width of a gap between the portion of the sensor body through which the Hall-Effect sensor is sensing and the projections of the wheel.
