H22A1 Optical Sensor- SE-739-D

Get the high-quality H22A1 at the best price in India.

The H21A_ and H22A_ series of opaque photointerrupters are single channel switches consisting of a Gallium Arsenide infrared emitting diode and a NPN silicon photo transistor 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.

H22A1 Features:-
High Gain
3mm Gap between LED and Detector
Polycarbonate case protected against ambient light APPLICATIONS
Copiers, Printers, Facsimilies, Record Players, Casette Decks, Optoelectronic Switches
