Agilent Unveils Optical Proximity Sensor for Mobile Appliances

8/31/2004 - Agilent Technologies (NYSE: A) introduced a miniature, low-cost optical proximity sensor to enable a variety of applications in compact mobile devices. In mobile phones, for example, Agilent's proximity sensor enables an automatic change from loudspeaker to earpiece mode when the phone is placed near the ear. 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.

"The proximity sensor is another example of Agilent's ability to apply optoelectronic technology leadership to the mobile device arena," said Kee Hane Ngoh, vice president and general manager of Agilent's Infrared Products Division. "This innovative product will add new convenience and performance features to mobile phones and other mobile applications."

Agilent's HSDL-9100-021 optical proximity sensor is specifically optimized for size, performance and ease of design in mobile appliances. Its small footprint (7.1 x 2.75 mm and only 2.7 mm high) is ideal for space-constrained applications, and it offers a variable detection range from approximately zero to 60 mm (2.4 inches) that allows manufacturers to easily customize 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 C to +85 C temperature range.

U.S. Pricing and Availability
The HSDL-9100-021 proximity sensor is available now through Agilent's direct sales channel and worldwide distribution partners. It is priced at $0.91 each in 50,000-unit quantities. More information is available at
