DESCRIPTION
The ISTS100, ISTS200 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.

FEATURES
l High Gain
l 3mm Gap between LED and Detector
l Polycarbonate case protected against ambient light

APPLICATIONS
l Copiers, Printers, Facsimilies, Record Players, Casette Decks, Optoelectronic Switches
