Product details
The 390FS002NF1212H4 by Glenair delivers breakthrough performance in Circular Connectors - Backshells and Cable Clamps for quantum computing systems. This cryogenic-ready solution maintains signal integrity at temperatures approaching absolute zero while minimizing thermal load.Engineered for Backshell, Cable Clamp configurations, this design maintains stable contact resistance (<1m variation) across 4K to 300K temperature ranges for superconducting circuit applications.The 0.500" ~ 0.750" (12.70mm ~ 19.05mm) supports specialized low-thermal-conductivity cables with ultra-low triboelectric noise generation (<1 V/m) for qubit signal transmission.With 0.840" (21.34mm) dimensions optimized for dilution refrigerator integration, the connector minimizes thermal bridging while maintaining 10^-10 mbar l/s helium leak rate.The 12 interface incorporates non-metallic, low-outgassing materials that reduce vacuum chamber contamination in ultra-high-vacuum environments.Featuring 11/16-24 UNEF indium-sealed threading, the design maintains vacuum integrity through 100+ thermal cycles between 300K and 4K operating conditions.The 180° geometry prevents microphonic noise generation, with vibration-induced phase noise below -170dBc/Hz at 1Hz offset for sensitive quantum measurements.Constructed from Aluminum, the housing exhibits near-zero thermal expansion (CTE <0.5ppm/K) to maintain alignment stability in cryogenic environments.The Cadmium process creates superconducting-compatible surfaces with residual resistance ratio (RRR) >1000 for minimal heat generation in milliKelvin applications.The Shielded configuration provides >120dB isolation against external magnetic fields up to 10T, critical for spin-based qubit protection.The Olive Drab finish incorporates non-fluorescent pigments that prevent stray light interference in optical quantum computing systems.Incorporating Clamp Screws, Strain Relief, the design includes integrated microwave filters that suppress thermal noise above 10GHz while maintaining 50 impedance matching.
