Request Information
The Weld or Braze Installation Instrumentation/Power Feedthrough, item #: 9809-01-W, is a versatile assembly designed for transferring electrical power, gases, or fluids across a hermetic chamber while maintaining a hermetic seal and electrical isolation. Often referred to as 'pass-throughs', these CeramTec feedthroughs not only ensure leak-free performance in high and ultra-high vacuum environments but also withstand high temperatures, cryogenic conditions, high pressure, and aggressive chemical exposures. With a DC voltage rating of 500V and an operating temperature range from -80 to 450ºC, these feedthroughs cater to diverse applications including semiconductor processing, particle accelerators, furnaces, analytical and in-vacuum coating equipment, satellite instrumentation, and X-ray detection. The design allows flexible installation, insulation, and conductor material choices, with options for push-on contacts available in the catalog's Accessories section.

Additional Information

Additional Information

 N/A

In addition to remaining leak-free in high and ultra-high vacuum, many of Ceramaseal® feedthroughs can accommodate:

  • High temperatures
  • Cryogenic temperatures
  • High pressure
  • Aggressive chemicals

A feedthrough is basically defined by the requirements for installation, insulation, and conductor material. The method of interconnection is flexible and left to the customer’s discretion. A selection of push on contacts can be found in the Accessories section of this catalog.
