Hermetic connectors
Hermetically sealed connectors are used in many applications where gas leakage into or out of equipment must be avoided.
Sealing is a very complex science itself, as it involves many physical aspects including mechanical design, materials science, surface science, and fluid behavior.
Hermeticity is one of the toughest challenges that design engineers face when specifying the connectors needed for their device, since their applications require the tightest sealing that will not just keep dust and water out but will provide a barrier to gases down to the molecular level, i.e., gas tightness.
Our Hermetic Connector Solutions
Our hermetically sealed connectivity solutions are well-known not only for their reliability but also for their long lifespan and durability.
Fischer Connectors’ founder, Walter Werner Fischer, developed the world’s first high-quality sealed connector for use in industrial applications in the ‘50s, and the first hermetic feedthrough connector for a vacuum chamber in 1964. No wonder that hermeticity is one of our flagship technologies, making our company brand, in the eyes of design engineers worldwide, synonymous with high-reliability connectivity in demanding and harsh environments.
Engineers designing applications requiring high-hermeticity performance choose gas-tight connectors from our high-performance product range.
