Product details
Optimized for quantum computing applications, 3M's 10268-R20CS sets new standards in D-Shaped Connectors - Centronics. This cryogenic connector system maintains nanoscale signal integrity at 4K temperatures, enabling reliable interconnects for superconducting qubit control systems in next-generation quantum processors.The Outer Shroud Contacts architecture employs non-magnetic materials and special thermal contraction matching to prevent microphonic noise in dilution refrigerator environments.Available in Receptacle configurations, these connectors support 50 impedance matching with less than 0.1dB insertion loss at millikelvin temperatures.With 68 filtered contacts, this series enables simultaneous DC bias and microwave control signal routing for multi-qubit systems.The 2 row arrangement incorporates superconducting shielding that reduces crosstalk below -120dB for sensitive quantum state measurements.Panel Mount, Through Hole options include ultra-high vacuum compatible versions that maintain 10^-11 Torr integrity in cryogenic measurement systems.Employing Press-Fit methods, these connectors achieve thermal anchoring that prevents heat leakage into cryogenic stages while maintaining signal fidelity.The Housing/Shell (M2.6) incorporates cryogenic thermal breaks that minimize heat conduction while maintaining mechanical stability in multi-stage refrigerators.Key Shielded include precision alignment guides and kinematic mounting for reproducible connections in quantum computing research setups.Gold plating has been specially formulated to maintain superconducting properties while preventing oxidation in cryogenic environments.Atomic-level controlled 30.0µin (0.76µm) ensures consistent contact properties through thousands of thermal cycles between 300K and 10mK.
