Vacuum Systems

Standard and custom flange vacuum feedthroughs, hermetic seals, and cable harnesses for high-vacuum conditions

Capable of creating true hermetic sealing technology, hermetic cable harnesses and hermetic wire feedthroughs in vacuums as high as 10-10 Torr, our vacuum flange feedthroughs have been chosen by leading research and industrial vacuum facilities for more than 20 years. We offer both off-the-shelf and highly-customized feedthroughs that meet the most stringent leakage and low-outgassing specifications.

Ideal Applications

  • Mixed bundle DuctorSeal® feedthroughs get your signal, thermocouple and power lines through a single vacuum chamber penetration.
  • Hermetic seal to fully populated rigid PCB boards, bringing multiple signal, power and air lines through a single vacuum chamber port.
  • Signal and power feedthrough assemblies for Maldi-TOF Spectrum Analyzer.
  • Multi-connector PotCon® Portplate flanges ship fully tested and ready to bolt onto the vacuum chamber. They achieve multiple quick electrical connection points through a single bulkhead hole with configurations for any thermocouple vacuum feedthrough connector or flange.

Technical Advantages

  • Vacuum feedthroughs designs that can accommodate up to 500 conductors at lengths up to several hundred feet.
  • Low outgassing epoxy (0.25% TMA, 0.00% CVCM) available in wire feedthrough, PotCon, StudSeal™ and fiber optic configurations.
  • Direct sealing of shielded conductors to any vacuum feedthrough flange design.
  • One hundred percent leak tested with typical leakage rates less than 1x10-9 cc-He/sec.
  • High voltage applications to 35 kV.
  • Decades of experience building fully connectorized hermetic and non-hermetic cable assemblies.
  • Cryogenic designs for temperatures down to -270ºC (3 K).
  • Vacuum bake-out services available.
