unless otherwise specified.

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 I_C(ON)
