News ReleaseAvago Technologies Announces New High Temperature C-Shaped Encoder Module for Brushless DC MotorsLow-Cost Six-Channel Encoder Module Provides Advanced Motion Control Detection and Easy Integration into Industrial Motors San Jose, CA - Avago Technologies announced the addition of a new compact high temperature six-channel optical incremental C-shaped encoder module for Brushless DC motors used in industrial and factory automation equipment. Avago's miniature AEDT-9340 encoder module is priced competitively and designed to enable the reduction in overall motor sizes. This latest addition to Avago's family of easy to install optical encoders, which is designed to fit easily in round encoder housings, provides motor manufacturers with advanced motion control detection. Avago is a leading supplier of analog interface components for communications, industrial and consumer applications. Avago's AEDT-9340 encoder module includes a lensed LED source and a detector IC enclosed in a small plastic package to offer better switching accuracy (± 1º mechanical commutation) than conventional Hall sensors. When used with a codewheel, this low-cost module detects rotary position. Moreover, due to a highly collimated light source and a unique photodetector array, this module is extremely tolerant to mounting misalignment. Typical industrial automation applications where the AEDT-9340 encoder can be used include robotic devices, textile machines, machine tools, and food and packaging machines. 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. Moreover, the integrated commutation channel output (U, V and W) in the AEDT-9340 is just as reliable as Hall sensors. Usage of Hall sensors adds to motor length, design complexity and assembly costs. Avago's six-channel AEDT-9340 optical incremental encoder has integrated commutation output channels (U, V, W), two channel quadrature outputs (A, B) and a third channel index output (I). This ungated index output is a positive index pulse that is generated once for each rotation of the codewheel. Features:
U.S. Pricing and Availability Avago's AEDT-9340 optical encoder module is priced at $21.50 in 1,000 unit quantities and available now in sample and production quantities. The AEDT-9340 is available through Avago's direct sales channel and worldwide distribution partners. |
