ABSTRACT:
An apparatus and method is provided for attaching a gear tooth sensor to an object, such as an engine block of an automobile. A clamping bar and a deformable conical washer are associated with a tubular portion of the sensor in such a way that rigid attachment of the clamping bar to the engine block, such as through the use of a threaded bolt, deforms the conical washer into a generally flat shape and, in the process, causes a distal end of the tubular portion of the sensor to move away from a target by a predetermined distance. Prior to deforming the deformable washer between the clamping bar and the engine block, the sensor is moved into contact with a rotatable target, such as a gear. The distal end of the in contact with the target, the clamping bar is used to compress and deform the washer so that the deformation of the washer causes the distal end of the tubular portion to move away from the target by a predetermined amount that results in an accurately set gap between a magnetically sensitive component within the sensor and the teeth of the rotatable target.
