An assembly which provides for the transfer of electrical power, gases or fluids from outside a hermetic chamber to the inside. Feedthroughs can provide both a hermetic seal and electrical isolation from the chamber wall. Feedthroughs are sometimes referred to as 'pass-throughs'.
CeramTec feedthroughs provide the solutions for applications requiring hermeticity and electrical isolation.

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.
