FEATURES
• Opaque housing
• Low cost
• .035” apertures
• High I
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.
