DESCRIPTION

The H21B_ and H22B_ series of opaque

photointerrupters are single channel switches

consisting of a Gallium Arsenide infrared

emitting diode and a NPN silicon photo

darlington mounted in a polycarbonate housing.

The package is designed to optimise the

mechanical resolution, coupling efficiency,

ambient light rejection, cost and reliability.

Operating on the principle that objects opaque to

infrared will interrupt the transmission of light

between an infrared emitting diode and a photo

sensor switching the output from an "ON" state to

an "OFF" state.

FEATURES

l High Gain

l 3mm Gap between LED and Detector

l Polycarbonate case protected against

ambient light
