In the category of hermetic connectors destined for use in harsh environments and especially in civil and military aeronautics applications, SOURIAU offers a very wide range of products compliant with numerous standards such as EN3646, EN2997 and MIL-DTL-38999. The hermetic connectors benefit from the advantages of their specific technology, manufacturing process and quality control.
The SOURIAU spirit: first-class customer service, product quality and logistics
In the exclusive world of the aeronautics industry, SOURIAU has a reputation for listening to its customers’
needs, maintaining a high level of manufacturing quality and operating a remarkably efficient logistics
organization. This organization ensures that lead times and delivery dates world-wide are scrupulously
respected, either directly or through the network of authorized distributors. Thanks to their product stock,
distributors are in a position to supply connectors for equipping prototypes or for maintenance requirements.
Large families of standard products and custom products
Arnaud Calvet, Product Manager for hermetic connectors: “The large families of standardized connectors
which we manufacture for the aeronautics sector are also available in hermetic versions, across the whole
range of shell sizes and pin configurations. As well as this, we’ve added specific products in response to
customer demand, like feedthroughs, thermocouple connectors and crimp contact versions.”
A bright future for SOURIAU hermetic connectors
Arnaud Calvet: “In aeronautics, the market for hermetic connectors is experiencing strong demand growth
for a large number of types of equipment including the aircraft’s internal electronics which has to be
protected from the intrusion of fluids from the exterior. And we are seeing an increasing number of sensors
(for pressure, temperature, speed vibration, strain etc.) being used in all parts of the aircraft as well as
requirements for hermetic connectors for the actuators of the landing gear, the wing flaps and stabilizers, the
flight controls and motor electronics.”
A proven technology
The hermeticity between the customer’s equipment and the SOURIAU connector is located at two points. The
first point is where the connector is attached to the equipment; the second is situated between the contacts and
the shell. In the manufacturing process for the hermetic connectors, the traditional insulator is replaced by an
insulator made of glass. A sintered wafer in the format of the shell and matching the contact arrangement is
placed in an autoclave and melted at a temperature of 1000°C. Under the effect of the heating and cooling
cycles, the glass retracts and creates total hermeticity between the shell and each contact.
A promising outlook for SOURIAU hermetic connectors
Arnaud Calvet: “Other markets for hermetic connectors are emerging in industry and aerospace thanks to
their compact size and because they have no rear accessories, they weigh less.
These are new opportunities which we are able to serve immediately.”
