San Jose, Calif. Avago Technologies says it has introduced the industry's first reflective encoder with an analog output. The AEDR-8320 high-resolution miniature surface-mount (SMT) optical encoder, which provides precise positioning information and direction sensing, is suitable for space-constrained industrial and office automation applications including pick and place machines, robotic equipment, optical disk drives, card readers, printers and copiers.
With dimensions of 6.50 x 4.20 x 1.69 mm (LxWxH), the AEDR-8320 optical SMT reflective optical encoder can operate over a wide temperature range of -10°C to 70°C. The optical encoder offers a two channel analog output that provides a resolution of 180 lines per inch (LPI) for rotary and linear movement control. The two channel analog outputs can achieve even higher resolutions through interpolation. The optical encoder can achieve resolutions of 2.2 to 10 microns 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 encoder series also incorporates an LED light source and photo detector IC in a single leadless package, and uses reflective technology to sense rotary or linear position. The encoders can be interfaced directly with most signal processing circuitries to provide design-in flexibility and easy integration into existing systems. The devices can also 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.
