Encoder montageRenishaw offers a wide range of precision position feedback systems for a diverse range of linear and rotary motion applications.

From our range of robust magnetic encoders for incremental and absolute requirements, through to high speed optical linear encoders and precision optical angle encoders, we can meet your motion system requirements, including ultra-high vacuum (UHV) applications. Renishaw also presents RESOLUTE™, a true absolute, fine pitch optical encoder system that has excellent dirt immunity and an impressive specification that breaks new ground in position feedback. All systems have an established reputation for ease of set-up and installation, plus minimal cost of ownership.

If you require the ultimate accuracy in linear position feedback then look at our range of interferometer-based laser encoders.

 Highlights

FASTRACK™ linear optical encoder system FASTRACK™ linear encoder scale system montage

A revolutionary track-mounted linear encoder scale system that combines ±5 µm/m accuracy with the ruggedness of stainless steel, and the quick and easy installation of a carrier-type encoder system.
