DESCRIPTION
This series of photointerrupters are dual channel switches consisting of two Gallium Arsenide infrared emitting diodes and two NPN silicon photo transistors mounted in a "side by side" configuration on opposite sides of a 2.5mm wide slot. Dual channels enable direction of travel sensing. The transmissive housing reduces possible interference from ambient light and provides dust and dirt protection. In addition the ISTS822S, ISTS832S have 0.25mm apertures in front of the phototransistors, While the ISTS822SD, ISTS832SD have the same sized apertures in front of both emitters and phototransistors

FEATURES
● Single or Double apertures for High Resolution
● 2.5mm Gap between LED and Detector
● Dual channels "side by side"

APPLICATIONS
● Copiers, Printers, Facsimilies, Record Players, Cassette Decks, VCRs
