ABSTRACT:
This invention relates generally to the field of motion detection sensors, and in particular to a system and method for adjusting the position of a printed circuit board relative to a focusing element. The invention includes a housing having a front opening and an interior cavity. A focusing element is located within the front opening and the detector is coupled to a printed circuit board located within the interior cavity. A cover is coupled to the printed circuit board and disposed within the interior cavity. A cam is operatively coupled with the cover and the printed circuit board for adjusting the position of the printed circuit board such that the detector's position is adjusted relative to the focusing element.
