Optical encoders offer full OEM package
A series of incremental optical encoders (with integral bearing) provides all the elements required for their easy installation in a manufacturer's housing.
Agilent Technologies has introduced a series of incremental optical encoders (with integral bearing) that provides all the elements required for their easy installation in a manufacturer's housing Agilent AEDA-3300 series optical encoder helps customers reduce their manufacturing and R and D costs and eliminates the need for purchasing additional supporting components

Dust-tight absolute optical encoders keep it clean
Agilent Technologies has developed its first absolute optical encoder products that provide position information without requiring shaft movement.
Modular encoder is absolutely cheaper
The industry's smallest high-speed "plug-and-play" absolute encoder is claimed to reduce assembly time by half and cut costs for industrial automation systems by as much as 40%.
As the AEDA-3300 series encoders are rated for operation in the -40 to +125C temperature range, they are ideal for industrial applications ranging from servo and stepper motors to automation equipment, such as robotic arms and wafer handling machines.
AEDA-3300 optical encoders are available in resolutions from 600 through 4096 cycles per revolution, at speeds up to 12,000rev/min, and operating frequencies up to 1MHz.
Quadrature decoding can provide a maximum of 16,384 counts per revolution.

Compact absolute encoder can count revolutions too
A new module adds motor-shaft revolution-count capability to the Agilent AEAS-7000, the industry's smallest high-speed, plug-and-play absolute encoder.
Compact encoders have all resolutions covered
Agilent Technologies has a new series of ultraminiature, high-resolution, three-channel optical incremental encoder modules.
Outputs are two-channel quadrature with a third gated index channel, and the encoder comes with an integrated RS422 differential line driver.
Most optical encoders are supplied in several diameters, based on limitations in code wheel and interpolation technology (the higher the resolution, the larger the code wheel diameter).
But the Agilent AEDA-3300 series of encoders are single diameter regardless of resolution.
The total package size is 17mm in diameter by 24mm high for the version designed for manufacturers of housed encoders.
This means that the encoder engine will fit within an 18mm diameter optical encoder package.
For motor manufacturers incorporating an optical encoder as part of a complete motor assembly, Agilent also offers a version with a mounting plate, with dimensions of 28mm in diameter by 27mm high.
No special alignment tool is required, as the AEDA-3300 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.
"Our new incremental optical encoders 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", said Chong Khin Mien, Vice President for the Motion Control Products Division in Agilent's Semiconductor Products Group.
"With these 'one-size-fits-all-resolutions' encoders, customers save development time by using the same design for their entire range of housed encoder resolutions".
Samples of the various configurations of Agilent AEDA-3300 series optical encoder engines are immediately available from Agilent's direct sales channel and worldwide distribution partners.
Higher-resolution encoders in the AEDA-3300 series, with resolutions from 2500 to 20,000 cycles per revolution, are expected to be available in the first quarter of 2006. Request a free brochure from Avago Technologies ...
