Abstract
A low cost assembly comprising only three major components: a circuit board assembly, a molded plastic housing and a molded plastic cover. The plastic parts are transparent polycarbonate (natural 'Lexan') wherein the housing has an integrally molded optical quality lens. Mounting features are integrally molded on the housing and cover. The circuit board assembly uses a common board, trace pattern and terminals and can be either a source or detector by appropriate selection of electronic components mounted to the board. A plurality of rounded bosses on the housing and larger round recesses in edges of the circuit board provide a light interference fit between housing and board to firmly hold the board in place and provide correct orientation of the board relative to the housing. The board may be readily removed and replaced for field repair of the sensor.
