ABSTRACT:
A disk sensing optics assembly is mounted directly on the register circuit board of an electronic energy meter. The molded optics assembly includes an central cavity adapted to receive a discontinuous rotating shutter, and pockets on either side dimensioned to hold and position pairs of light emitters and detectors on opposite sides of the shutter to detect speed and direction of rotation of the shutter. Apertures through the rear of the housing are adapted to position and secure the electrical leads from the light emitters and detectors within the housing and are soldered to the register printed circuit board. Positioning means integral with the housing and register circuit board space, position, and secure the disk sensing optics and the assembly to the register circuit board with the electrical leads properly positioned for soldering to the circuit board.
