Hermetic Glass-Feedthrough Connectors (For Vacuum Equipment)

A hermetic connector provides an electrical connection between the interior and exterior of a vacuum component while maintaining the vacuum seal. Hermetic connectors can be made from various insulation materials, such as ceramics (including glasses) or plastics. Kyocera offers hermetic connectors using glass materials. Kyocera's glass hermetic connectors are compact, enable high-density terminals, and can be used at RF frequencies up to 110 GHz, which takes advantage of glass's low dielectric constant.

Kyocera's glass hermetic connectors can be used at frequencies up to 110 GHz for various applications, including communications infrastructure.

Non-Magnetic Connectors

Non-magnetic connectors are available using molybdenum as the pin material.

Kyocera's hermetic connectors have been used in beam-position monitors (BPMs) deployed within particle accelerators because of their hermeticity, compact size, and low transmission loss in high-frequency bands. Miniaturization makes it possible to install many hermetic connectors on the outer periphery of the cylindrical flange. SMA connector interface simplifies cable attachment/detachment.

Kyocera's representative hermetic glass-feedthrough connectors include D-sub terminals, RF terminals for high frequency, and coaxial terminals.
D-sub terminals can be designed with a narrow pitch, thanks to glass sealing, supporting up to 50 pins.
In addition, glass with a low dielectric constant provides excellent high-frequency characteristics.
