Ultra-Miniature Optical Encoder Provides Wide Range of Resolutions

June 1, 2006

Avago Technologies offers low-cost solution for industrial and motor-control applications.


SAN JOSE, Calif. /BUSINESS WIRE/ -- Avago Technologies, one of the world's largest privately held semiconductor company, announced the addition of a low-cost ultra-miniature transmissive optical encoder module to its family of products. Avago's new compact AEDA-3200 optical encoder module is a "one-size-fits-all" product that is designed for applications requiring resolutions from 2500 to 7500 cycles per revolution (CPR). The device provides motor manufacturers, system integrators, and equipment manufacturers with a versatile and cost-effective solution that also minimizes their development costs.

Avago, the industry-leading supplier of motion control encoders, offers the AEDA-3200 in a top-mounting package. The device was designed for a variety of motors used in industrial and medical equipment applications. Some of the targeted applications include robotic arms, wafer-handling machines, and fluid control in medical equipment.

The AEDA-3200 module features three-channel optical incremental outputs, with an RS-422 line driver for clean signal propagation to provide resolutions up to 30,000 CPR after 4X decoding. The miniature device, which is about the size of a sewing thimble, can operate in temperatures ranging from –40°C to 125°C.

Designed as a modular package, the AEDA-3200 comes complete with codewheel and sensor, making it easy for manufacturers to design the part into their motor designs.

"The AEDA-3200 is part of our ongoing commitment to provide cost-effective, high-performance solutions to help our customers deliver their products to market faster," said Hassan Hussain, general manager, Motion Control Products Division at Avago Technologies. "We offer significant performance and cost benefits to customers in a wide variety of optical encoder market segments, giving them competitive products suited to their R&D and manufacturing capabilities."

Avago's AEDA-3200 is part of the AEDA-3300 optical-kit-encoder offering announced in March. The AEDA-3200 module encoder is a lower-cost option featuring resolutions from 2500 to 7500 CPR. The AEDA-3300 is a kit encoder featuring resolutions from 600 to 20,000 CPR and does not require an alignment tool for installation. Both of these encoder series are designed for a variety of motors used in industrial applications.

Key Product Features and Benefits

  • Ultra-miniature size is ideal for those motor control applications that require a high-resolution encoder in a small area. The AEDA-3200 can easily fit into an 18 mm housed encoder. The top-down version is 17 mm in diameter, with a height of 24 mm.
  • Encoder module offers ease of assembly and significantly reduces assembly costs using a specially designed alignment tool (HEDS-8940).
  • Five resolution options from 2500 to 7500 CPR provide customers with "one-size-fits-all resolution" to help significantly reduce development time and costs.
  • Integrated line driver enables flexible design without signal loss up to 1000 ft.
  • Operating frequency of up to 1 MHz, which is "about twice the frequency of competing products," allows the encoder to perform at high CPR and at high RPM.

U.S. Pricing and Availability
Pricing for the AEDA-3200 ranges from $39 to $43, each in quantities of 1000. Samples of the AEDA-3200 are available from Avago's direct-sales channel and worldwide distribution partners.
