Medium Power Feedthroughs are designed to transmit high voltage, high current, or a combination of both in demanding vacuum environments. Built with proven, time-tested designs, these feedthroughs optimize electrical performance while ensuring durability and safety.

When space permits, ceramic surfaces are extended to maximize strike and creep distances. For compact systems, convoluted ceramics are used to enhance insulation without significantly increasing the insulator length. All air-side ceramic surfaces are glazed with a high-temperature glass coating, reducing surface roughness and minimizing contamination risks.

Most designs include exposed conductors on both the air- and vacuum-sides. Air- and vacuum-side connectors are available separately for most products unless otherwise specified.
