H21B1 H21B2 H21B3

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
