H22B3 - Fairchild Semiconductor

H22B3 PHOTODARLINGTON OPTICAL INTERRUPTER SWITCH

The H22B1, H22B2 and H22B3 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 opaq.
