Multi-Pin Threaded Feedthrough ('Mil Spec') - Weldable, Double-Ended

These multi-pin instrument feedthroughs have circular threaded connectors on the air-side and vacuum-side. They meet MIL-C-5015 standards (so-called MIL SPEC feedthroughs). Each Alumel® or molybdenum wire conductors is alumina insulated and rated for 700V at a maximum current of 10A. Both the air-side and a ceramic insulated vacuum-side plugs are included with the feedthrough. Feedthroughs of this type are designed for welding into a suitable through-hole in a flange.

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.
