Cryogenic Shielding: significant shielding techniques for harness assemblies

Shielding techniques for cryogenic shielding from Cryoconnect

Utilising constructions in silverplated copper, stainless steel, manganin, constantan and phosphor bronze, we can configure cable assemblies with a wide range of shielding constructions by design

Individually shielded:

  • Single wires
  • Twisted pairs
  • Twisted triples
  • Twisted quads

Overall/selectively shielded:

  • Braid shields
  • Foil shields

We can also include by design:

  • Ground wires of varying gauges and alloys inserted between signal wires to minimise cross-talk and provide an opportunity to minimise the thermal load
  • Additional carbon shield coating to create a triboelectric effect

Determining the shielding termination specification may require distinction between 0V returns, chassis grounds and faraday shielding. For all connector types, both circular and rectangular, we can provide 360 degree RFI/EMC shielding within our range of encapsulated backshells. By design we can reduce the pin count and therefore mass by introduction of a busbar to pull up individual grounds, or return lines to terminate to dedicated pin or connector shells.

  • 360 degree shielding for all connector types, including nano density
  • Inclusion of busbar in backshells to common grounds by design
  • Isolation of grounds and faraday shields by design
