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.  
FEATURES  
• Opaque housing  
• Low cost  
• .035” apertures  
• High IC(ON)
