ABSTRACT:
A sensor assembly includes a housing and a plurality of lenses. The lenses are connected with a lens carrier by a plurality of releasable connector elements. A circuit board is disposed on the lens carrier. The circuit board has a black coating. A connector assembly connects the circuit board with an electrical conductor. The connector assembly includes a body portion and a flange portion. The flange portion engages a recess in the sensor housing to hold the body portion of the connector assembly against axial movement relative to the sensor housing. A retainer extends from a cover portion of the sensor housing into engagement with the flange portion of a connector assembly to hold the flange portion against rotation to thereby block unauthorized access to the interior of the sensor housing. A light detector is movable relative to a light source to enable the distance from the light source to a location from which reflected light is received by the detector to be adjusted.
