Mil-C-5015 Circular - CF Feedthroughs

10 AMP, Circular Feedthroughs on CF flanges

These feedthroughs are mounted on CF Flanges that incorporate the industry standard "captured copper gasket" sealing principle, making it easy to mount to your existing CF Flange ports.

Mil-DTL-5015 Interface

Circular hermetic power feedthroughs are designed to meet Mil-DTL-5015 specifications. These feedthroughs are available in either a 3-pin or 6-pin configuration. Gold-plated pins are in a straight through pin-to-pin design and are hermetically sealed and electrically insulated in a stainless steel shell using the latest in glass-ceramic bonding technology.

Ultrahigh vacuum cable assemblies with PEEK connectors and Kapton® insulated 18 AWG cables are available to meet the demands of UHV environments. They are fitted with a captured stainless steel vented screw that provides a means of securely locking them to their mating feedthrough. Air-service cable assemblies use standard Mil-DTL-5015 connectors. Custom air-service cable assemblies are available on request.

Mil-DTL-5015 feedthroughs are sold individually or as kits, where each kit contains one feedthrough and one each of both vacuum and air side cable assemblies.
