Product description:


The H22B1, H22B2 and H22B3 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

rejection, cost and reliability. The gap in the housing provides a means of interrupting the signal with an opaque material, switching

the output from an ON to an OFF state.
