Multi-Pin Threaded Feedthrough (Mil-Spec) - KF Flange, Double-Ended

These multi-pin instrument feedthroughs have circular threaded connectors on the air-side and vacuum-side. They meet MIL-C-5015 standards (commonly called 'Mil-Spec' feedthroughs). Each Alumel® wire conductor is alumina insulated and rated for 700V at a maximum current of 10A. Both the air-side and vacuum-side plugs are included with the feedthrough. The KF flanges are sealed with centering and O-ring combination (not included) making them high vacuum compatible.
