Product details
The R85049/88-21Z03 by TE Connectivity Aerospace, Defense and Marine 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, Banding configurations, this design maintains stable contact resistance (<1m variation) across 4K to 300K temperature ranges for superconducting circuit applications.The 0.812" (20.62mm) supports specialized low-thermal-conductivity cables with ultra-low triboelectric noise generation (<1 V/m) for qubit signal transmission.With 1.642" (41.71mm) dimensions optimized for dilution refrigerator integration, the connector minimizes thermal bridging while maintaining 10^-10 mbar l/s helium leak rate.The 21, G interface incorporates non-metallic, low-outgassing materials that reduce vacuum chamber contamination in ultra-high-vacuum environments.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 Zinc Nickel 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 Black finish incorporates non-fluorescent pigments that prevent stray light interference in optical quantum computing systems.Incorporating Self Locking, the design includes integrated microwave filters that suppress thermal noise above 10GHz while maintaining 50 impedance matching.
