DESCRIPTION
The H21A series are 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.
NOTES:
1. Dimensions for all drawings are in inches (mm).
