New infrared emitter-detectors and reflective proximity sensor components

7 March 2007 Opto-Electronics

Avago Technologies has added four new high-performance infrared (IR) sensor component families to its line. The ASDL-4xxx, 5xxx and 6xxx are three series of high-performance IR emitter and detector products and the new APDS-91xx is a family of high-speed reflective proximity sensors.

Avago's new series of IR emitters and detectors can be used in devices such as smoke detectors, IR spotlights for cameras, and remote control devices. The integrated reflective proximity sensors are for use in applications that require high-speed switching for object detection or proximity sensing, such as packaging and assembly equipment, beverage dispensing machines, copiers and printers.

The ASDL IR emitters and detectors incorporate Avago's aluminium gallium arsenide on GaAs (AlGaAs/GaAs) LED technology and are available in T1, T13/4 and Side Look standard packaging. They are optimised to operate at wavelengths of 870 and 940 nm to provide design flexibility.

Targeted for high-speed non-contact and fast speed switching industrial and office automation applications, the APDS-91xx series reflective sensors incorporate an infrared LED and a phototransistor in a single integrated module that has been designed to operate in low temperature environments. Its compact design provides detection at distances from 8 mm to 12 mm.
