Harness for cryo systems and instruments

To avoid temperature transfer to the instruments since making measurements at infrared and sub-millimetre wavelengths, parts of the instruments have to be cooled to near absolute zero.

In the following example is given to underline our expertise in this field and the complexity of Cryo harness systems.

Features / technical details

  • Number of harness bundles: 40
  • Number of connectors on bundles connected: 90
  • Number of wire connections installed: 9.500
  • Harness Mass: 19,5 Kg

Applications

  • Steelwires and Brasswires AWG 38 (0,1 mm Diameter)
  • Qualified Temperature Range: 10°K to 300°K
