San Jose, Calif. Avago Technologies has introduced a series of high-performance
three-channel optical incremental encoders for use in a wide range of office and industrial automation applications. The HEDM-5540 encoder series maintains the form, fit and function of its predecessor HEDx-5xxx series for easy conversion while providing increased resolutions up to 1000 counts per revolution (CPR). Typical applications include printers, plotters, tape drives, positioning tables and automatic handlers.
The HEDM-5540 series includes a lensed LED source, an integrated circuit with detectors and output circuitry, and a new high-temperature Mylar codewheel. The HEDM-5540 series offers a third channel index output in addition to two channel quadrature This index output is a 90 electrical degree, high true index pulse which is generated once for each full rotation of the codewheel, offering more accurate position control. The series is specifically designed for easy mating to a wide range of connectors
from a variety of manufacturers. The device can operate in the temperature range of -40°C to 100°C to meet most industrial temperature requirements.
The TTL compatible HEDM-5540 series, housed in a 30 x 41.1 x 18.3-mm package, offers up to a 100 kHz frequency response. The device is RoHS compliant.
Pricing: $25.52 each in quantities of 10,000.
