PotCon: Hermetic Wire Feedthrough

The PotCon® line of hermetic feedthroughs incorporates standard connectors and wire harnesses in a single, fully-sealed housing. PotCon features circuits that can disconnect at the pressure bulkhead or vacuum Portplate, allowing for easy mating and un-mating.

The PotCon hermetic seals can be used on a wide range of connectors including:

  • Common military connectors including: Mil-C-5015, Mil-C-38999, Mil-C-26482, Mil-C-24308, Mil-DTL-83513, Mil-DTL-32139 and more.
  • Plastic connectors from manufacturers like Tyco, Molex, Souriau, Amphenol and more.
  • D-Sub connectors including regular and standard density (HDM), high density (HDD), Micro-D and Nano-D configurations.
  • Coaxial connectors including 10-32, BNC, MCX, MHV, Type N, SHV, SMA, SMC, TNC, UHF and more.
  • Capability to turn IP68 waterproof connectors from Brad Harrison, Mencom, Fischer and Lemo into fully hermetic PotCons.
  • Waterproof.
  • Thermocouple.
  • High current and high voltage.

Sample configurations:

  • Connector-to-connector - connectors on both sides of the hermetic seal.
  • Connector-to-wire - connector on one side of the hermetic seal and simple wire or complex cable harnessing on the other side.
  • Connector-to-terminal - connector on one side of the hermetic seal and solder cups, PCB pin-header or pogo-pins on the other.
  • PotCon hermetic connectors are 100% electrically and hermetically tested to ensure the highest quality. PotCon seals can perform in high voltage (30kV), high pressure (15,000 psi) and high vacuum (1x10-10 Torr) environments.



PotCon PBTR is our most common PotCon series. Either ordered through our catalog or custom configured, the mating capability of these hermetically sealed connectors has proven valuable in the space simulation field where bench top testing is a key requirement. Connectors can be clocked at the customer's discretion, and these connectors are available in thermocouple configurations. View Specifications.
