Subminiature Power-DTM Feedthroughs on ISO Flanges

These feedthroughs are mounted on ISO KF or LF Flanges that incorporate the industry standard "centering-ring O-ring" sealing principle, making it easy to mount to your existing KF/LF Flange ports.

Power-D ISO KF / LF Feedthroughs

Power-DTM Interface

Accu-Glass Power-DTM hermetic, high-current power feedthroughs, are designed to IEC 807-2 and DESC 85039 combination subminiature-D interface specifications.

Three (3) and five (5) pin feedthroughs, with Au, plated NiFe alloy pins, rated to 20 Amps per pin, are hermetically sealed and insulated into 304 stainless steel subminiature-D shells using the latest in glass-ceramic / metal bonding technology. Mating cable assemblies with PEEK polymer connectors and Kapton® insulated leads are also available to meet the rigorous demands of UHV environments.

Vacuum and air-side cable assemblies, individual connectors, contacts, wiring tools, and other accessories can be found starting on page 40. Custom Power-DTM solutions are also available on request. Please contact the factory for more information.
