Encoder modules offer 'one-size-fits-all-resolutions' solution

6 October 2004 Opto-Electronics

Agilent Technologies has designed a series of ultra-miniature, high-resolution, three-channel optical incremental encoder modules to meet the requirements of manufacturers of general-purpose housed encoders and integrated motor-encoder assemblies, and for incorporation in applications ranging from pick-and-place machines to automotive systems.

The Agilent AEDA-3200 series encoders measure 17 mm in diameter by 24 mm high and offer customers a 'one-size-fits-all-resolutions' solution. Using the Agilent encoder, the customer needs to produce only one design for all resolutions, says the manufacturer. Until now, different resolutions had required different encoder sizes or mounting arrangements. Many motor manufacturers, machine manufacturers and system integrators prefer a modular encoder that fits within their own integrated housing, says Agilent.

The AEDA-3200-T (for top-down mounting) features resolutions from 2500 to 20 000 cpr (counts per revolution) and an integrated RS422 differential line driver permitting signal lines up to 1200 m. The devices feature operation from -40 through +125°C. Agilent will soon also offer the AEDA-3200-B bottom-up mount versions with heights of only 12 mm.

The AEDA-3200 series uses transmissive encoder technology to sense rotary position. The sensor consists of an LED light source, photodetector IC, interpolator IC and line driver, with outputs consisting of two square waves in quadrature and a gated index pulse.
