Absolute rotary encoder RESOLUTE™ FS REXA30

opticalnon-contactDRIVE-CLiQ

What is RESOLUTE FS? RESOLUTE FS (Functional Safety) is a true absolute, fine pitch optical encoder system that has excellent dirt immunity, and an impressive specification that breaks new ground in position feedback. It is the world's first absolute encoder capable of 29 bit resolution at 7 500 rev/min. Ultra low SDE and jitter result in a rotary encoder system that outperforms any other encoder in its class. Certified to SIL2 and PLd for use in functional safety applications. What is REXA30 ring? REXA30 is a one-piece stainless steel ring with 30 µm pitch absolute graduations marked directly on the periphery. Its larger cross-section allows for the reduction in all installation errors apart from eccentricity, which is easily corrected using the average result of two Resolute readheads. Featuring total installed accuracy up to ±1 arc second, zero coupling losses, and exceptional repeatability. REXA30 is available in a range of sizes (Ø52 mm to Ø417 mm), all of which have a large internal diameter for flexible integration.
