Hermetic Cable Feedthrough – Hermetic Cable Seals

Hermetic Cable Seal Feedthrough Applications

Hermetic cable seal feedthroughs are used in many applications and industries. An epoxy hermetically sealed cable feedthrough is a sensible solution if you don’t need to disconnect at the bulkhead. A cable seal feedthrough that is hermetically sealed with epoxy offers a more flexible solution that saves space. These cable seal feedthroughs pass conductors in a cable harness through a chamber wall with no vacuum or pressure loss. An epoxy sealed wire feedthrough also eliminates issues with voltage drop, contact resistance, and other electrical problems. The conductor is continuous through the cable seal feedthrough without solder terminations, so the cable seal offers reliable performance. Epoxy hermetic seals even allow for the use of different types of conductors and cables in the same feedthrough, adding yet another advantage.
We can design and produce cable seals for every industry from medical facilities and labs to airport equipment. Every cable seal we manufacture goes through a rigorous test process, including pressure leak tests, helium testing, high voltage testing, and/or continuity testing. This ensures every seal we ship is robust.

We seal all types of cables, including coaxial, twisted pair, multiconductor, fiber optic, shielded cables, and even multiple shields like HDMI and triax cables. If you need a custom vacuum cable seal, we offer flexible, cost-effective designs manufactured to the exact specifications of your project.

Continuous feedthroughs can also be used in older systems when retrofitting is necessary. Adding new instrumentation or sensors to an existing chamber can be a time-consuming and difficult task when using standard connectors or when the opening of the chamber wall does not allow additional conductors. A wire seal feedthrough can be adapted to add more conductors to work with limitations in an existing system.

Every hermetic wire seal is tested with pressure and / or helium leak tested.  In addition, all hermetic wire seal feedthroughs are hipot and / or continuity tested to ensure the wire seal feedthrough is correctly wired.
