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.
Extreme/Custom Design N/A
  • Multiple feedthrough flange assemblies
  • 940-pin header assembly
  • Corona-free designs to 180 kV DC
  • Currents in excess of 2,500 Amps
  • Pressures to 30,000 psig
Applications N/A A few of the many applications in which these feedthroughs are commonly used are:
  • Semiconductor processing equipment
  • Particle accelerators
  • Furnaces
  • Analytical equipment
  • In-vacuum coating
