H21B4 General Description

The H21B4, H21B5 and H21B6 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 hous.
