Product details
The 1907940 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 3 superconducting architecture minimizes heat leakage. Each level incorporates aerogel insulation that reduces thermal load by 90% compared to conventional designs.With 1 non-magnetic contacts, the block preserves qubit coherence. Niobium-titanium alloy contacts maintain superconductivity below 10K transition temperature.45° (135°) Angle with Board alignment facilitates vacuum chamber feedthroughs. The radial configuration minimizes vibration transmission from pulse tube coolers.Precision-rated for 10 A bias currents, the contacts exhibit zero resistance. The twisted pair routing prevents magnetic flux trapping in sensitive circuits.The 300 V isolation withstands microwave pulse signals. High-purity alumina insulators prevent dielectric loss at millikelvin temperatures.Accepting 12-26 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.
