Abstract:
1. A sensor assembly comprising a sensor housing, a circuit board disposed in said sensor housing, a light source disposed within said sensor housing, a light detector disposed within said sensor housing, a first lens at least partially disposed in said sensor housing and through which light from said light source is transmitted to a location outside of said sensor housing, a second lens at least partially disposed in said sensor housing and through which light transmitted from said light source and reflected from the location outside of the housing is transmitted to said light detector, a first one of said light source and light detector being connected with said circuit board, a carriage which is disposed in said sensor housing and is movable relative to said circuit board, a second one of said light source and light detector being connected with said carriage for movement with said carriage relative to said circuit board, a retainer which is connected with said carriage and said circuit board to retain said carriage in a position to which said carriage is moved relative to said circuit board, and a connector assembly which is connected with said circuit board and is adapted to be connected with an electrical conductor, said connector assembly being movable relative to said sensor housing between a secured position in which said connector assembly engages a portion of said sensor housing to retain said connector assembly against movement relative to said sensor housing along a central axis of said connector assembly and a release position in which said connector assembly is movable relative to said sensor housing along the central axis of said connector assembly.
