RESOLUTE™ UHV absolute encoder readhead

Renishaw: RESOLUTE™ absolute optical encoder with BiSS serial communications

RESOLUTE is a revolutionary new true absolute, fine pitch optical encoder system, with excellent dirt immunity, offering an impressive specification that breaks new ground in position feedback.

RESOLUTE’s patented technology combines 1 nm resolution with exceptionally high speed, up to 100 m/s (36 000 rev/min), reading from a range of high accuracy linear tape and spar scales or angle encoder rings.

RESOLUTE uses a unique single optical absolute track (a world first) with a nominal pitch of 30 μm, combined with sophisticated optics. This ensures wide set-up tolerances, very low sub-divisional error of ±40 nm and ultra-low noise (jitter) of less than 10 nm RMS, resulting in better velocity control performance and rock solid positional stability.

Reliability is assured by RESOLUTE’s excellent dirt immunity, built-in separate position checking algorithm and IP64 sealed readhead with wipe-clean recovery.

RESOLUTE is available with a variety of serial protocols. Please contact your local representative for the latest list.
