D-Type Feedthrough, Consisting of 3 Power Pins on a KF50 Flange.
D-Type Feedthrough, Consisting of 3 Power Pins on a KF50 Flange.
D-Type Feedthrough, Consisting of 5 Power Pins on a NW63 LF Flange.
These Power-D ISO 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. Accu-Glass Power-D™ — 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 Ni-Fe 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-D™ solutions are also available on request. Please contact the factory for more information.
