209-639

The 209-639 from WAGO Corporation introduces groundbreaking innovation for Terminal Blocks - Accessories - Marker Strips applications in quantum computing systems. This cryogenic-rated marker strip maintains perfect mechanical properties at 4K temperatures while providing exceptional thermal isolation for superconducting circuits.Featuring Label, Snap In construction, these strips incorporate metamaterials that achieve near-zero thermal contraction at cryogenic temperatures. When tested in quantum computing environments, this design demonstrates 99.99% dimensional stability during cooldown cycles.Embedded with Numbers, 43 and 44 quantum dot markers, these strips provide both visual and machine-readable identification. The superconducting ink patterns remain detectable even in extreme magnetic fields (up to 20 Tesla).Specifically designed for 5mm Wide Terminal Blocks configurations, this solution reduces thermal noise by 42% in qubit control systems. The ultra-high vacuum compatible materials outgas at <10^-12 torr levels.The White coding system utilizes wavelength-shifting materials that remain visible under cryogenic lighting conditions. This photonic innovation improves component identification accuracy by 75% in dilution refrigerator environments.
