Optical proximity sensor makes the shortlist
An optical proximity sensor for mobile appliances developed by Agilent Technologies was one of the finalists for the EE Times Annual Creativity in Electronics (ACE) awards.
High brightness on surface mount LEDs.
Agilent Technologies has introduced a series of surface-mount LEDs designed and qualified specifically for automobile interior and exterior lighting applications.
Hot-pluggable transceiver for Fibre Channel
Agilent Technologies has announced volume availability of its 2Gbit/s small-form-pluggable (SFP) fibre-optic transceiver for Fibre Channel storage area networks (SANs).
Current phone models require user intervention to switch between loudspeaker and earpiece mode.
The new device can also detect the opening and closing of popular clamshell mobile phones and can activate the power-saving mode in notebook computers.
The proximity sensor is ideal for paper-edge detection in printers, photocopiers and fax machines.
It can also be used to switch on/off home appliances, such as table lamps, without the need for mechanical switches.
There are many other potential applications within the consumer, industrial and automotive markets.
Agilent's HSDL-9100-021 optical proximity sensor is specifically optimised for size, performance and ease of design in mobile appliances.
Its small footprint (7.1 x 2.75mm and only 2.7mm high) is ideal for space-constrained applications, and it offers a variable detection range from approximately 0 to 60mm that allows manufacturers to easily customise the device for multiple applications.
The proximity sensor is packaged in a metal housing to shield the LED emitter from the photodetector.
The surface-mount, lead-free package eliminates optical crosstalk between the LED emitter and the light sensor to assure high signal-to-noise ratio for reliable performance.
The unit also features an integral ambient light filter and guaranteed performance over the -25 to +85C temperature range.
The HSDL-9100-021 proximity sensor is available now through Agilent's direct sales channel and worldwide distribution partners. Request a free brochure from Avago Technologies ...
