H21A2 General Description

The H21A1, H21A2 and H21A3 consist of a gallium arsenide infrared emitting diode coupled with a silicon phototransistor 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.

H21A4 General Description

The H21A series are gallium arsenide infrared emitting diode coupled with a silicon photodarlington in a plastic housing. The pckaging system is designed to optimize the mechanical resolution, coupling efficiency, ambient light rejection, cost and rliability. The gap in the housing provides a means of interrupting the signal with an opaque material, switching the output rom an "ON" to an "OFF" state.
