Cryogenic Cable Options

MicroFlex Coax Cable

Flexible Superconducting Niobium-Titanium Coax (Patent Pending)

Niobium-titanium coax cable offers the ultimate solution for maintaining signal integrity while minimizing heat loads at low temperatures. When cooled below its superconducting transition temperature of 9.2K, the NbTi center conductor provides a zero resistance wire for signal transmission while the superconducting outer conductor utilizes the Meissner effect to protect the transmitted signal from interference. We offer this cable turnkey with soldered connector terminations (unlike commonly used crimp-style connectors) which provides a robust low-loss connection at the connector-cable junction.
