Hermetic Connectors

  • Hermetic Connectors

Hermetic Connectors provide a vacuum or leak-tight seal, insulate or channel electricity, and prevent the ingress of contaminants. They are made of ceramic, glass, or metal materials and joined in a specific configuration by furnace brazing. 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.
