1803947

Designed for quantum computing environments, Phoenix Contact's 1803947 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 Cable Housing variant utilizes superconducting niobium-titanium alloys that transition below 9.3K, enabling zero-resistance connections in dilution refrigerator applications.With 3 filtered feedthroughs, this solution delivers 80dB attenuation at 10GHz while preserving qubit coherence times above 100 s.When paired with COMBICON GMSTB, IC and MSTB Series, the assembly demonstrates negligible thermal conductance (<1 W/K) while supporting 1000+ coaxial connections in quantum processor packaging.The Green anodization provides effective thermal radiation shielding while maintaining ultra-high vacuum compatibility below 10^-9 Torr.
