Agilent Debuts High-resolution Optical Encoders for Printers, Scanners

3/26/2004 - Agilent Technologies Inc. (NYSE: A) introduced two high-resolution optical encoders designed to increase the performance of home and office printers and image scanners. With the increasing interest in digital photography and other graphic-intensive applications, consumers expect higher quality graphic performance from today's mid- to high-end printers, copiers and scanners. The new encoders from Agilent's Semiconductor Products Group offer this higher resolution with the size needed for high-volume printers.

Optical encoders detect the position, speed and direction of components such as print heads in inkjet printers, imaging drums and rollers in laser printers and photocopiers, and scan heads in optical scanners. Greater precision in detecting these parameters results in higher quality printing and higher resolution scans.

"As the clear leader in optical encoders for the office automation market, customers expect Agilent to deliver leading-edge performance in combination with high-quality and high-volume manufacturing," said Chong Khin Mien, vice president and general manager of Agilent's Motion Control Products Division. "As we expand our motion control products to address the industrial automation market, we remain committed to maintaining our leadership for printers and scanners."

Agilent's HEDS-973X-350 optical encoder offers a digital output with 480 LPI (lines per inch) resolution, matching the highest resolution provided by any manufacturer for office automation applications. Agilent's HEDS-971X-150 is an analog-output encoder providing 360 LPI resolution, higher resolution than any analog encoder designed for office automation applications. The HEDS-971X-150 delivers an effective resolution of up to 1,440 LPI when used with external interpolation techniques.

The HEDS-971X-150 operates over the +15 C to +45 C temperature range and requires only a single 5V supply. The HEDS-973X-350 operates from -40 C to +85 C and can run off a 3.3V up to 5V supply. Both versions feature a 40 kHz frequency count, making them compatible with high-speed operation. The encoders are supplied in a lead-free module with dimensions of only 20.2 mm by 12.6 mm by 10.8 mm. Combining a highly collimated light source and a unique photodetector array, the module is extremely tolerant to mounting misalignment. The standard modules are designed for use with an 11 mm optical radius code wheel or linear code strip.

U.S. Pricing and Availability
The Agilent HEDS-973X-350 and HEDS-971X-150 optical encoders are priced at $8.35 each in 11,000- to 20,999-piece quantities. These devices are available now through Agilent's direct sales channel and worldwide distribution partners.
