H22B1 - PHOTODARLINGTON OPTICAL INTERRUPTER SWITCH

Description

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.

Features

  • Opaque housing.
  • Low cost.
  • .035" apertures.
  • High IC(ON) © 2002 Fairchild Semiconductor Corporation Page 1 of 6 6/13/02.
