Renishaw: RESOLUTE absolute optical encoder UHV (Ultra High Vacuum) with BiSS serial communications 32BIT/100DIA Compatible Readhead RA32BVA100B50V
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.
