ABSTRACT:
A fixture containing a compact rotational position sensor mounted directly to a driving contrivance for detecting movement of a member. The fixture comprises an attachment flange having a central bore with a front face for engagement with the driving contrivance. The front face has a recess proximate to the central bore and an opening from the outer surface of the attachment flange in communication with the recess. A control shaft passes through a central bore whereby the control end is attached to the member and the free end is attached to the driving contrivance. The sensor for detecting the rotational position of the control shaft is disposed in the recess whereby the attachment flange conceals the sensor when it is attached to the driving contrivance.
