Opto Interrupter

EAITRBA1

Features

․Fast response time

․High analytic

․High sensitivity

․Cut-off visible wavelength λP=940nm

․Pb Free

․This product itself will remain within RoHS compliant version.

Description

The EAITRBA1 consist of an infrared emitting diode and an NPN silicon phototransistor, encased

side-by-side on converging optical axis in a black thermoplastic housing. The phototransistor receives

radiation from the IR only . This is the normal situation. But when an reflecting object close to ITR ,

phototransistor receives the reflecting radiation .For additional component information, please refer to

IR4204-10 and PT4204-6B/H26.

Applications

․Mouse Copier

․Switch Scanner

․Floppy disk driver

․Non-contact Switching

․For Direct Board
