Palo Alto, Calif.— HEDR-5300 optical encoder is a two-channel quadrature incremental optical encoder said to be ideal for motion detection in printers, plotters, tape drives, positioning tables, and other applications where space is a premium. The unit is designed for quick and easy mounting to a motor shaft by using a self-aligning mounting boss.
Palo Alto, Calif.— HEDR-5300 optical encoder is a two-channel quadrature incremental optical encoder said to be ideal for motion detection in printers, plotters, tape drives, positioning tables, and other applications where space is a premium. The unit is designed for quick and easy mounting to a motor shaft by using a self-aligning mounting boss. It features a resolution of 160 counts per revolution; a position accuracy of 25 arc minutes; pulse width error of 15 electrical degrees; and a phase error of 8 electrical degrees. Electrical output consists of two square waves in quadrature, providing the capability of measuring position, speed, rotational direction, and other parameters. Hewlett-Packard
