Avago’s AEDS-964x modules are used with a transmissive code strip to detect linear motion or with an 11-mm-optical-radius transmissive code wheel for detecting rotary motion. Their primary application is to provide position, speed and direction feedback to the circuitry controlling inkjet print head carriages, as well as paper patch control. They offer excellent performance and reliability in conventional inkjet printers, photo printers, multifunction printers, plotters, fax machines and scanners.
