Absolute rotary encoder RESOLUTE™ UHV REXA30

opticalnon-contactIP30

What is RESOLUTE UHV? RESOLUTE UHV brings absolute encoder technology to Ultra-High Vacuum applications, allowing customers to achieve higher throughput, reduce risks of damage and increase dependability. RESOLUTE outperforms all other absolute encoders that are designed for UHV environments. Capable of 32-bit resolution at 8 500 rev/min, RESOLUTE provides a specification that breaks new ground in encoder technology. 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. The non-contact format eliminates backlash, shaft wind-up (torsion) and other mechanical hysteresis errors that are inherent in traditional enclosed encoders.
