H21A6 Datasheet (Fairchild Semiconductor) - PHOTOTRANSISTOR OPTICAL INTERRUPTER SWITCH

H21A6 - PHOTOTRANSISTOR OPTICAL INTERRUPTER SWITCH

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 mean
