H22B4 Datasheet (Fairchild Semiconductor) - PHOTODARLINGTON OPTICAL INTERRUPTER SWITCH

H22B4, PHOTODARLINGTON OPTICAL INTERRUPTER SWITCH

The H22B4, H22B5 and H22B6 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.
