Avago Technologies Adds to Incremental Optical Encoder Family With Versions Featuring up to 20,000 Cycles-Per-Revolution Performance.SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif. -- Miniature Encoders Offer One-Size-Fits-All Resolutions, Allow Customers to Reduce Costs by Creating One Design Platform for All Resolutions Avago Technologies Avago Technologies is an American company which was earlier the semiconductor products division of HP and later Agilent Technologies, before being spun off into a distinct legal entity. It holds more than 2,000 patents. today announced that it has expanded its family of incremental Additional or increased growth, bulk, quantity, number, or value; enlarged. Incremental cost is additional or increased cost of an item or service apart from its actual cost. 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 An electromechanical device that uses feedback to provide precise starts and stops for such functions as the motors on a tape drive or the moving of an access arm on a disk. and stepper motors A motor that rotates in small, fixed increments and is used to control the movement of the access arm on a disk drive. Contrast with voice coil. (hardware) stepper motor to automation equipment, such as robotic arms A robotic arm is a robot manipulator, usually programmable, with similar functions to a human arm. The links of such a manipulator are connected by joints allowing either rotational motion (such as in an articulated robot) or translational (linear) displacement. 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 (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. for resolutions less than 10,000 cpr, and 650 kHz for resolutions between 10,000 and 20,000 cpr.

Most optical encoders are supplied in several diameters, based on limitations in code wheel and interpolation interpolation In mathematics, estimation of a value between two known data points.

The Avago AEDA-3300 series encoders are the same diameter regardless of resolution, with a total package size of 17 mm diameter by 24 mm high for the version designed for manufacturers of housed encoders. This means that the encoder engine will fit within an 18 mm diameter optical encoder package. For motor manufacturers incorporating an optical encoder as part of a complete motor assembly, Avago also offers a version with a mounting plate (28 mm diameter by 27 mm high). No special alignment tool is required, since the AEDA-3300 encoder is supplied in a package in which the code wheel has been pre-aligned to the encoder optics. The integrated bearing stage also allows for a greater tolerance to customer shaft position variations, without affecting the encoder performance. U.S. Pricing and Availability Samples and production quantities of the various configurations of the AEDA-3300 series optical encoder engines are immediately available from Avago's direct sales channel and worldwide distribution partners. Pricing ranges from $44 to $71 each in 3,900-piece quantities, for resolutions from 600 to 20,000 cpr.
