Sealed feedthroughs are specialised components that allow electrical signals, fluids, or other media to pass through the wall of a sealed system—such as a vacuum chamber, pressure vessel, or cryogenic enclosure—without breaking the seal.
In simpler terms, they create a leak-tight path through a barrier while keeping two environments (for example, vacuum inside and atmosphere outside) completely isolated from each other.
Key Points:
Primary Function: Maintain the integrity of the sealed environment while allowing controlled transfer of power, signals, gases, or fluids.
Applications: Commonly used in vacuum systems, pressure chambers, semiconductor equipment, aerospace, and research labs.
Types:
Electrical feedthroughs – carry power or data signals.
Fluid/gas feedthroughs – allow gases or liquids to pass through.
RF and coaxial feedthroughs – transmit high-frequency signals.
Thermal feedthroughs – transfer heat or coolant.
Sealing Methods: Usually achieved with materials like glass-to-metal, ceramic-to-metal, or epoxy seals that ensure vacuum-tight performance and long-term durability.
