San Jose, Calif. Avago Technologies has expanded its family of miniature reflective incremental optical encoders with a new high resolution encoder. Touted as the industry's smallest, the AEDR-8400-14x surface-mount optical encoders measure 3 (L) x 3.28 (W) x 1.26-mm (H).
The AEDR-8400-14x optical encoders provide up to 318 lines per inch (LPI) resolution and feature a two-channel quadrature digital output for directional sensing. These high resolution optical encoders are transistor-transistor logic (TTL) compatible and incorporate an LED light source and photo detector IC in a single leadless package.
The optical encoders use reflective technology to sense rotary or linear position. They 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. These devices are insensitive to axial play and maintain performance and accuracy over a wide variation in the gap between sensor and code wheel or strip, said the company.
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, said the company. They may be used 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.
The devices operate over a wide temperature range of -20° to 85°C. The series is RoHS compliant.
