RENISHAW: RESOLUTE™ absolute optical readhead with BiSS ® serial communications RL26BAT050B30A
RESOLUTE™ is a true-absolute fine-pitch optical encoder system with excellent metrology performance. Patented RESOLUTE encoder 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 encoder systems use a single optical absolute track 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. The RESOLUTE system ensures reliability with excellent dirt immunity, built-in separate position-checking algorithm and IP64 sealed readhead with wipe-clean recovery. RESOLUTE encoders are available with a variety of serial protocols. Contact your local Renishaw representative for details.
