Abstract
A sensed element is disclosed for incorporation into an apparatus that includes a rotatable shaft. The sensed element includes at least one sensor-detectible feature detectible by a sensing device for use in measuring a rotational speed of the shaft, a base portion coupled to the shaft so as to rotate with the shaft, and a projection extending from the base portion. The projection is engageable with a portion of the apparatus to limit movement of the sensed element along the shaft. The projection may also aid in positioning the sensed element within the apparatus during installation and removal of the sensed element.
