Subminiature-D or Sub-D
UHV 9, 15, 25, and 50-pin Subminiature-D (Sub-D) hermetic 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).
Multi-pin Sub-D Vacuum 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.
Introducing the HV Bulkhead-D multi-pin 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 multi-pin electrical 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.

| Notes |
- Electrical ratings are maximum test values, with vacuum side at ≤ 1x10-4 Torr. Feedthroughs are intended for instrumentation applications carrying low level signal voltage and current.
- Per pin maximum @ 20°C. For proper heat dissipation, a maximum of 20% of pins on a feedthrough may carry the maximum pin current at any given time.
- PEEK is a polyether ether ketone thermoplastic. DAP is a glass-filled diallyl phthalate.
- Leak tested to 5x10-10 Standard cc/sec of He.
- Overall assembly ratings must be adjusted to that of its lowest rated component. For cryogenic service, the lowest recommended temperature is -200°C
- Unless designated a 'kit,' connectors and cable assemblies are not included with feedthrough and must be purchased separately.
