Glass-to-Metal Sealing

Conesys hermetic connectors are based upon glass-to-metal sealing technology,which offers reliability at an attractive cost.

This technology provides a high degree of performance in harsh environments that would typically cause resilient connectors to fail (from corrosion, high temperature, high pressure, etc.).

Hermetic technology is a good solution to reduce connector dimensions to a minimum. There are no rear parts, making the connectors completely flat (PCB applications).


Fields of Application

Military Applications

Conesys hermetic connectors meet design standards of MIL-DTL-38999, EN2997, MIL-C-26482, MIL-C-26500, MIL-C-5015, and MIL-C-24308.

Electronic Equipment

Hermetic connectors are designed with several configurations. Pin tail contact configuration is available for PCB soldering. Hermetic connectors can also be used for their very short dimensions.


With an adapted design, hermetic connectors can withstand pressure up to 1500 bars. Main applications include pressure sensors and connectors for fuel tanks.


The glass to metal sealing technology provides a barrier fully adapted to vacuum applications.

Fluid Hydraulics

Glass is an inert material, completely adapted to withstanding aggressive fluids like fuel, oil, skydrol, cooling fluid, and de-icing fluid. Conesys hermetic connectors are the obvious choice for engines and severe industrial environments.


Our hermetic connectors can withstand the effect of salt corrosion through adapted materials and plating. Our con- nectors are therefore well adapted to marine environments.

Custom solutions

Based on standard designs, our hermetic connectors can be designed for special and dedicated applications.
