ASDL-4263
High Eciency T-1 ¾ (5mm) Infrared (940nm) Lamp
Data Sheet
Description
ASDL-4263 is a Infrared emitter that is optimized for high
eciency at emission wavelength of 940nm and narrow
viewing angle. This device is designed for high radiant
intensity and low forward voltage applications. It is en-
capsulated in T1-3/4 (5mm) package and is suitable for
high performance replacements of standard emitters.
Applications
• Smoke Detector
• IR Remote Control for Consumer Devices
• IR Remote Control for Industrial Equipment
• Photo-interrupters
• Reective Applications
• Infrared Illuminator Security Camera
