... DESCRIPTION The H22B4, H22B5 and H22B6 consist of a gallium arsenide infrared emitting diode coupled with a silicon photodarlington in a plastic housing. The packaging system is designed to optimize the mechanical resolution, coupling efficiency, ambient light rejec- tion, cost and reliability. The gap in the housing provides a means of interrupting the signal with an opaque material, switching the output from an “ ...
