Avago Technologies, a privately held semiconductor company, recently introduced an enhanced series of cost-competitive ultra-small optical encoder modules with resolutions of up to 360 lines per inch (LPI) – believed to be the highest in the industry. According to Avago, these new encoder modules make it possible for manufacturers to produce more compact inkjet printers, photo printers and all-in-ones, that can provide higher quality images that today's customers want. The AEDS-964x series are a drop-in replacement for Avago's AEDS-962x series.

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.

Features
