Description

What is RESOLUTE ETR? RESOLUTE ETR (Extended Temperature Range) 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 32-bit resolution at 8 500 rev/min. This brings all the benefits of the revolutionary RESOLUTE absolute, fine pitch angle encoder to harsh, low-temperature applications. With operation guaranteed down to -40 °C (-40 °F) in non-condensing environments, RESOLUTE ETR is ideally suited for use in demanding applications such as telescopes, scientific research and defence and aerospace. 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.
