Multi-Pin Threaded Feedthrough (Mil-Spec) - CF 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. With CF flanges (air-side cable disconnected) and suitable connections made to the ceramic insulated vacuum-side plug, these feedthroughs are bakeable to 350°C and are UHV-compatible.
