Encoder modules improve motor feedback
Small six-channel optical incremental C-shaped encoder modules are designed for brushless DC motors used in industrial automation applications.
Avago Technologies has announced its first series of small six-channel optical incremental C-shaped encoder modules for brushless DC motors used in industrial automation applications Avago's AEDB-9340 series modules, which include a codewheel with an optical radius of 15mm, are designed to reduce overall motor size and fit easily into round encoder housings

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%.
This latest addition to Avago's optical encoder series provides housed encoder manufacturers with an integrated encoder that is easy to assemble and offers better switching accuracy (+/-1 degree mechanical commutation) than conventional Hall sensors.
Typical industrial automation applications where the AEDB-9340 can be used in brushless DC (BLDC) motors include food and beverage processing equipment, packaging and textile machinery, and machine tools.
Other application examples include robotic devices, industrial printers, plotters, metal processing, and wood working equipment.

Compact encoders have all resolutions covered
Agilent Technologies has a new series of ultraminiature, high-resolution, three-channel optical incremental encoder modules.
The demand for improved motor control by housed encoder and motor manufacturers is driving the trend towards wide scale use of optical encoders with integrated commutation output over Hall devices in BLDC motor applications.
A growing number of designers are choosing optical encoders for their motor designs because they are less expensive and just as reliable as Hall sensors, which add to motor length, design complexity and assembly costs.
Avago's AEDB-9340 series enables designers to develop motors that are smaller and easier to align reducing the time required for housed encoder assembly.
These new encoder modules also provide superior switching accuracy due to much lower hysteresis when compared with Hall sensors, which require larger housings and are more difficult to align.
The commutation signals of one or more pole pairs are configurable by changing the codewheel pattern.
Moreover, with the use of transmissive technology, the encoder provides better and more accurate feedback as the BLDC motor torque ripple is reduced.
Overall, the AEDB-9340 provides designers with a powerful solution that helps to simplify housed encoder integration.
Avago's AEDB-9340 series optical encoder modules are priced at $29 each in 1000-unit quantities and are available now in sample and production quantities.
An evaluation kit, which includes an alignment tool and connector cable, is available.
Both products are available through Avago's direct sales channel and worldwide distribution partners. Request a free brochure from Avago Technologies ...
