Standard BNC feedthroughs are an economic, general purpose coaxial solution, where defined impedance and high voltage are not required. Up to 4 feedthroughs will fit on a single 40CF or 40KF flange, either single or double-sided and in-vacuum cables are available for both types.

The 50 Ohm BNC feedthroughs are suitable for high frequencies. The double-sided version can be used up to 4GHz. Air-side sockets are included and in-vacuum cables are available for both versions.

The industry standard air side connectors are shielded and EMC compliant. All air side connectors are metric threads. Used in combination with vacuum side housing,  it is possible to achieve a fully shielded connection from air to vacuum.

Multiple feedthrough flanges are available as standard, CF and ISO-K, or custom.

Special versions, e.g. 9 pins on a 25KF flange or 25 pins on a 50KF flange require vacuum side connectors without the mounting screws while standard air side connectors will fit.
