Hermetic Connectors

  • Hermetic Connectors

Hermetic connectors are designed to prevent the ingress of air, gases and other liquids into the vacuum-sealed connector. They should be able to withstand extreme temperature variations, from approximately -100° to 200°C and resist damaging vibration. They also must withstand high pressures of 10,000 psi or more, ensuring a stable pressure differential on both sides of the assembly.  Common types of hermetic seals include metal-to-metal seals, ceramic-to-metal seals, and glass-to-metal-seals.

Extreme applications need electronic components that perform impeccably and retain their original properties, no matter the environment. BTC Electronic Components has the largest inventory of hermetic connectors in North America. If you need a hermetically sealed Connector, we are your one-stop-shop. We have the right hermetic connector that can stand up to the limits and stress for your application.
