ABSTRACT:
Embodiments of the present invention are directed to providing secure retention of the variable sensor and the rotational object to which it is attached for measuring rotation thereof. In one embodiment, a sensor retention apparatus comprises a rotational sensor including a sensor shaft which has a direction of insertion. The sensor shaft includes a retainer slot oriented nonparallel to the direction of insertion and extending from a first surface of the body through the sensor shaft to a second surface of the sensor shaft. A rotational member has a cavity shaped to receive the sensor shaft along the direction of insertion. The rotational member includes an interference slot disposed adjacent the cavity. A retainer member is configured to be inserted into the retainer slot of the sensor shaft of the rotational sensor and to include a protruded portion protruding from the second surface of the retainer slot into the interference slot of the rotational member. The protruded portion is deformed to form an interference contact with the interference slot of the rotational member.
