Description
The Rotator25 from MultiFields' 25mm Series is a high-performance closed-loop piezoelectric rotary stage engineered for ultra-compact integration in extreme environments. With a minimal footprint of just 25 × 25 × 14.5 mm and a total weight of 24 g, it is designed for precision positioning tasks in cutting-edge scientific research and cryogenic setups.
Crafted from pure titanium and BeCu, the Rotator25 is non-magnetic and compatible with magnetic fields up to 18 Tesla, enabling stable operation in high-field environments. Its construction also supports ultra-high vacuum (UHV) levels to 2E-11 mbar and temperatures as low as 30 mK, making it ideal for He3 or dilution refrigerator systems.
With a 360° endless rotation, dynamic torque up to 1.5 N·cm, and position sensing resolution down to 10 m°, the Rotator25 ensures precise control with exceptional repeatability (~50 m°). Optional configurations such as .HV, .ULT, .UHV, and .ULT.UHV versions allow easy adaptation to specialized experimental requirements.
