Feedthroughs

Components that allow the transfer of fluid, gas, mechanical motion or electrical power into a chamber isolated by an environmental difference; e.g., a high pressure or vacuum protective atmosphere.

Electrical feedthroughs transmit electrical current through the walls of a pressurized or vacuum system through a hermetic seal.
