Technical Data Sheet
Opto Interrupter
ITR8102
█ Features
․Fast response time
․High analytic
․High sensitivity
․Pb free
․This product itself will remain within RoHS compliant version
█ Descriptions
The ITR8102 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 object is in between ,
phototransistor could not receives the radiation.
█ Applications
․Mouse Copier
․Switch Scanner
․Floppy disk driver
․Non-contact Switching
․For Direct Board
