SAN JOSE, Calif.--(BUSINESS WIRE)--March 29, 2006-- Miniature Encoders Offer One-Size-Fits-All Resolutions, Allow Customers to Reduce Costs by Creating One Design Platform for All Resolutions

Avago Technologies today announced that it has expanded its family of incremental optical encoder engines that provide all of the elements required for easy installation in a customer-supplied housing. The new encoders include versions with resolution performance from 5,000 to 20,000 cycles per revolution (cpr).

Avago AEDA-3300 series optical encoders reduce manufacturing and R&D costs, and eliminate the need for purchasing additional supporting components. The AEDA-3300 series encoders are rated for operation in the -40 C to +125 C temperature range, so they are ideal for industrial applications ranging from servo and stepper motors to automation equipment, such as robotic arms and wafer-handling machines.

"Historically, housed encoders with resolutions above 10,000 cpr have been priced in the $500 range," said Chong Khin Mien, vice president for the Motion Control Products Division at Avago Technologies. "Our new incremental optical encoders provide twice the performance at less than one-fifth the price of traditional housed encoders. They offer significant performance and cost benefits to a wide variety of optical encoder market segments, including encoder manufacturers, motor manufacturers, system integrators and equipment manufacturers."

AEDA-3300 series optical encoders are now available in resolutions from 600 through 20,000 cpr, at speeds of up to 12,000 rpm (ranges from 10,000 rpm for 6,000 cpr to 1950 rpm for 20,000 cpr resolution), and operating frequencies up to 1 MHz for resolutions less than 10,000 cpr, and 650 kHz for resolutions between 10,000 and 20,000 cpr. Using quadrature decoding with the highest-resolution version can provide a maximum of 80,000 pulses per revolution (ppr). Outputs are two-channel quadrature with a third gated index channel, and the encoder comes with an integrated RS-422 differential line driver.
