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

These multi-pin instrument feedthroughs have circular threaded connectors on the air-side and meet MIL-C-5015 standards (commonly called 'Mil-Spec' feedthroughs). Each Alumel®, nickel, or molybdenum wire conductor is alumina insulated and rated for 700V at a maximum current of 46A. The air-side plug is included with the feedthrough but connectors for the vacuum-side wires are not. Feedthroughs of this type are designed for welding into a suitable through-hole in a flange.
