Avago Technologies Announces First Miniature Reflective Analog Optical Encoder for Industrial and Office Automation Applications.

Small Surface-Mount Encoder Series Provides 180 LPI Resolution

SAN JOSE, Calif. -- Avago Technologies, a leading supplier of analog interface components for communications, industrial and consumer applications, today announced the industry's first reflective encoder with analog output. Avago's AEDR-8320 high-resolution miniature surface mount (SMT) optical encoder, which provides precise positioning information and direction sensing, is ideal for use in industrial and office automation applications where space is constrained. This new analog reflective encoder is the latest addition to Avago's broad portfolio of miniature optical encoders.

With dimensions of 6.50 mm length by 4.20 mm width by 1.69 mm height, Avago's AEDR-8320 optical SMT reflective optical encoders can operate over a wide temperature range making them ideal for use in a variety of applications. The AEDR-8320 targets designers of pick and place machines, robotic equipment, optical disk drives, card readers, printers and copiers.

Avago's AEDR-8320 series offers two channel analog output that provides a resolution of 180 lines per inch (LPI) for rotary and linear movement control. In addition, its two channel analog outputs can achieve even higher resolutions through interpolation. The AEDR-8320 can achieve resolutions of 2.2 um to 10 um for linear movement and from 4096 counts per revolution (CPR) to 7840 CPR for rotary sensing, utilizing an external interpolation IC. These high resolution optical encoders also incorporate an LED light source and photo detector IC in a single leadless package, and uses reflective technology to sense rotary or linear position. Moreover, the AEDR-8320 encoder can be interfaced directly with most signal processing circuitries to provide design-in flexibility and easy integration into existing systems.

The AEDR-8320 series of reflective encoders provides accurate real-time position sensing that's superior to competing encoders in terms of duty, state and phase. They are also insensitive to axial play and maintain performance and accuracy over a wide variation in the gap between sensor and code wheel or strip. Additionally, the AEDR-8320 series can be used with a reflective code wheel to sense rotary position and velocity, or with a linear code strip to sense linear position and velocity.
