Subminiature-D or Sub-D

UHV 9, 15, 25, and 50-pin Subminiature-D (Sub-D) feedthroughs (vacuum feedthrough) are constructed with multi-pin arrangements per Mil-DTL-24308 (formerly Mil-C-24308) specification.   All pins are gold-plated and arranged in a straight-through pin-to-pin design.   Hermetically sealed and electrically insulated into a stainless steel shell using the latest in glass-ceramic bonding technology (ceramic feedthrough).

Sub-D Feedthrough Connectors and Assemblies

Ultrahigh vacuum compatible Sub-D wire assemblies are fitted with PEEK (polyether-etherketone) polymer connectors and Kapton® insulated ribbon cable to meet the rigorous demands of ultrahigh vacuum environments.  Each subminiature-D vacuum connector includes two (2) captured stainless steel socket head screws that securely lock a connector to its mating electrical feedthrough.  To eliminate virtual leaks, in-vacuum captured screws are vented where required.

HV Bulkhead-D Feedthrough Product Line

AGP's HV Bulkhead-D hermetic electrical feedthrough was developed for high-vacuum flat-chamber-wall applications where conventional ISO NW KF or LF flanges are either not available, or just not practical.   Our universal 2x3.5 inch rectangular flange, the Bulkhead-D flange, accommodates standard 9, 15, 25, or 50-pin subminiature-D electrical feedthroughs, and shares the same gasket and fastening accessories... providing simple and convenient interchangeability.

Subminiature-D, also referred to as D-Sub or Sub-D feedthrough assemblies with up to 250 pin configurations are routinely fabricated. Custom solutions with over 1,000 pins have also been engineered and produced.

Tip: Accu-Glass Products Conflat CF and/or ISO KF/LF Conical Reducers are ideally suited for the expansion of vacuum feedthrough capacity on smaller chamber flanges like fitting a 50-pin 4.50-inch CF flange mounted feedthrough using a 2.75-inch CF chamber port.   Click on the following links to access CF Conical Reducers, and/or ISO NW Conical Reducers.
