Product details
The 1789485 by Phoenix Contact pioneers new Terminal Blocks - Wire to Board technology for quantum computing applications. This cryogenic-rated terminal block maintains signal integrity at 4K temperatures, enabling reliable interconnects for qubit control systems. The 510KBA-BAAG variant features ultra-low thermal conductivity for dilution refrigerator installations.The 1 superconducting architecture minimizes heat leakage. Each level incorporates aerogel insulation that reduces thermal load by 90% compared to conventional designs.With 7 non-magnetic contacts, the block preserves qubit coherence. Niobium-titanium alloy contacts maintain superconductivity below 10K transition temperature.0.100" (2.54mm) spacing prevents cross-talk in multiplexed control lines. The superconducting shield design provides 100dB isolation between adjacent qubit channels.90° Angle with Panel alignment facilitates vacuum chamber feedthroughs. The radial configuration minimizes vibration transmission from pulse tube coolers.Precision-rated for 6 A bias currents, the contacts exhibit zero resistance. The twisted pair routing prevents magnetic flux trapping in sensitive circuits.The 150 V isolation withstands microwave pulse signals. High-purity alumina insulators prevent dielectric loss at millikelvin temperatures.Accepting 20-26 AWG superconducting wires, the termination preserves critical current density. The indium-plated interface ensures zero-contact-resistance joints.Through Hole installation minimizes thermal anchoring. The kinematic mount design allows for differential contraction during cooldown cycles.The Screwless - Spring Cage, Tension Clamp process occurs at room temperature before cooling. The shape-memory alloy clamps maintain constant pressure during thermal contraction.Interlocking (Side), Lever Actuated include integrated RF filters. The cryogenic RF chokes attenuate noise above 5GHz while passing DC bias currents.
