Avago Technologies Adds Lower Cost Solution to Ultra-Miniature Optical Encoder Module Family

Avago's new compact AEDA-3200 optical encoder module is a "one-size-fits-all" product that is ideal for applications requiring resolutions from 2,500 to 7,500 Cycles-Per-Revolution (CPR). This 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 which require high resolution, temperatures and frequencies include robotic arms, wafer handling machines, and fluid control in medical equipment.

The AEDA-3200 module features three channel optical incremental outputs with an RS422 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 is an encoder module that comes complete with codewheel and sensor, making it very 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 2,500 to 7,500 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 ideal 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. It is available in the following size:
Top down version: 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 2,500 to 7,500 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 1,000 feet.

· Operating frequency of up to 1 MHz, which is about twice the frequency of competing products, allows the encoder to perform at high cycle per revolution at high RPM.
