Surface-Mount Optical Encoder Series Provide Up to 318 LPI Resolution

Avago's AEDR-8400-14x series of high resolution optical encoders provide up to 318 lines per inch (LPI) resolution, have two-channel quadrature digital output for directional sensing, and are transistor-transistor logic (TTL) compatible. 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-8400-14x encoder can be interfaced directly with most signal processing circuitries to provide design-in flexibility and easy integration into existing systems. The AEDR-8400 series of encoders are an excellent choice for use in miniature motor applications, housed encoders, digital still cameras, scanners, printers, and a wide range of other office and industrial automation applications where space is limited.

Avago's AEDR-8400 series of reflective encoders provide 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. The AEDR-8400 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.

With the addition of the AEDR-8400-14x encoder, Avago can now provide designers of office and industrial automation applications with a choice of two miniature reflective optical encoder options. The higher resolution AEDR-8400-14x offers up to 318 LPI while the AEDR-8400-13x offers up to 254 LPI.
