71240-850CALF

The 71240-850CALF from Amphenol ICC (FCI) delivers breakthrough performance in Memory Connectors - PC Card Sockets for quantum computing applications. This cryogenic-ready connector system maintains signal integrity at temperatures down to 4K while providing ultra-low thermal conductivity.Supporting PCMCIA - CardBus, Type I, II, III interfaces, the connector enables reliable interconnects between room-temperature and cryogenic environments. Its thermal-break design minimizes heat leakage into superconducting circuits.The 68, 68 configuration has been optimized for qubit control signal distribution. The carefully spaced contacts prevent cross-talk in sensitive quantum measurement systems.Featuring Connector and Ejector architecture, this connector achieves vacuum compatibility down to 10^-9 Torr. The hermetic seals prevent outgassing contamination in ultra-high vacuum chambers.The Push In, Push Out mechanism enables operation with cryogenic gloves. The oversized controls provide positive engagement feedback in low-temperature environments.The Left release mechanism operates reliably in extreme cold. The thermal-isolated actuator prevents frost buildup during cryogenic operation.Designed for Surface Mount, Right Angle installation, the connector supports both dilution refrigerator and cryostat mounting. Its low-thermal-mass design minimizes cool-down time.Incorporating Card Guides, this connector provides magnetic shielding exceeding 80dB at DC. The mu-metal enclosure protects sensitive quantum states from external magnetic interference.The 0.654" (16.60mm) ultra-compact profile fits within tight cryogenic probe stations. The minimized cross-section reduces thermal loads in multi-layer quantum devices.The Reverse - Bottom option enables precision alignment for superconducting qubit chips. The kinematic mount provides micron-level repeatability for quantum coherence measurements.Utilizing Gold technology, the contacts maintain stable resistance through thermal cycling. The specialized plating prevents cold welding at cryogenic temperatures.With atomically-controlled 30.0µin (0.76µm), the contacts achieve consistent performance across all quantum states. The deposition process has been optimized for quantum coherence preservation.
