A rotary position sensor for measuring the position of a rotating shaft comprises an upper housing and a lower housing arranged to be attached to the upper housing. A barrel is rotationally mounted to the attached upper and lower housings and coupled to the shaft is arranged to be positionable within the attached upper and lower housings by the shaft. A potentiometer component is mounted to the barrel and to an electrical sub-assembly that measures the position of the barrel and in response generates a position signal.
