DESCRIPTION
The H21B1, H21B2 and H21B3 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.
FEATURES
• Opaque housing
• Low cost
• .035" apertures
• High I
