3069974

Designed for quantum computing environments, Phoenix Contact's 3069974 achieves unprecedented performance in Terminal Blocks - Accessories applications. Its cryogenic-compatible construction maintains contact resistance stability from 300K down to 4K with less than 5% variation.The Test Plug variant utilizes superconducting niobium-titanium alloys that transition below 9.3K, enabling zero-resistance connections in dilution refrigerator applications.With 17 filtered feedthroughs, this solution delivers 80dB attenuation at 10GHz while preserving qubit coherence times above 100 s.When paired with CLIPLINE FTPR Series, the assembly demonstrates negligible thermal conductance (<1 W/K) while supporting 1000+ coaxial connections in quantum processor packaging.The Gray anodization provides effective thermal radiation shielding while maintaining ultra-high vacuum compatibility below 10^-9 Torr.
