Product details
The 250-221 by WAGO Corporation 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 21 non-magnetic contacts, the block preserves qubit coherence. Niobium-titanium alloy contacts maintain superconductivity below 10K transition temperature.0.138" (3.50mm) spacing prevents cross-talk in multiplexed control lines. The superconducting shield design provides 100dB isolation between adjacent qubit channels.45° (135°) Angle with Board alignment facilitates vacuum chamber feedthroughs. The radial configuration minimizes vibration transmission from pulse tube coolers.Precision-rated for 8 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 16-24 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 - Push Button Clamp process occurs at room temperature before cooling. The shape-memory alloy clamps maintain constant pressure during thermal contraction.The Gray housing uses low-outgassing materials. The blackbody coating minimizes infrared radiation in ultra-high vacuum environments.
