Hermetic Connectors
Presentation
Based on glass to metal seal technology, SOURIAU offers hermetic connectors to cover applications which require
performances that supersede standard watertight connectors capability, such as high pressure, high temperature
variations resistance, secured hermetic protection, ...
In addition to the various connector standards on which this technology has been developed, SOURIAU supports
customers speci c needs, from a shell or contact change to more complex and innovative solutions.
This hermetic connectors catalog aims to give an extensive outlook of SOURIAU’s offering. After an overall view
of the hermetic technology, you will  nd a detailed description of each connector range speci cs features, as well
as dimensions and ordering details. The end of the catalog will give you a  avor of some of the various speci c
extensions. Enjoy the reading!
