Weldable RF Feedthrough

RF Power Feedthroughs are designed for transmission of RF power commonly used for induction heating.  Power ratings up to 35kW and frequencies up to 13.56MHz are available.

Non-Magnetic materials that are not susceptible to the effects of RF coupling are used in the construction of these feedthroughs.

Please note, when installing two 35kW/13.56MHz RF power feedthroughs side by side, their center to center spacing must be greater than 2.00 inches.  Adequate clearance between the feedthrough and any surrounding hardware must be allowed in order to avoid power coupling.

These RF feedthroughs feature high alumina ceramic, 1/4" or 3/8” OD copper tubing for water cooling, and 304L stainless steel components. We offer them mounted on weld adapters, CF flanges, and QF flanges.

Note: The electrical and thermal ratings specified are of safe operating limits determined by various factors including material properties, mechanical design, and the intended operating environment. All electrical ratings are based on operation with one side in dry atmosphere and the other side in vacuum of less than 1 x 10-4 Torr. All VacuCAD files as well as any dimensions shown or listed in our ordering tables do not include manufacturing tolerances and are provided for reference only.
