Original Press Release:
Agilent Technologies Introduces Miniature Incremental Optical Encoders With Up to 4,096 Cycles-per-revolution Performance
Agilent Technologies Inc. (NYSE: A) today 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&D costs and eliminates the need for purchasing additional supporting components. Since the AEDA-3300 series encoders are rated for operation in the -40 C to +125 C 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 4,096 cycles per revolution (cpr), at speeds of up to 12,000 rpm, and operating frequencies up to 1 MHz. Quadrature decoding can provide a maximum of 16,384 counts per revolution. Outputs are two-channel quadrature with a third gated index channel, and the encoder comes with an integrated RS-422 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 17 mm in 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, Agilent also offers a version with a mounting plate, with dimensions of 28 mm in diameter by 27 mm high.
No special alignment tool is required, since 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."
U.S. Pricing and Availability
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. Pricing ranges from $44 to $48 each in 2,500-unit quantities, for resolutions from 600 to 4,096 cycles per revolution.
Higher-resolution encoders in the AEDA-3300 series, with resolutions from 2,500 to 20,000 cycles per revolution, are expected to be available in the first quarter of 2006.
