Subminiature D Type Feedthroughs on Bulkhead Flanges

Subminiature D Type Feedthroughs on Bulkhead Flanges

The HV Bulkhead D feedthrough was developed for HV flat chamber wall applications where conventional ISO KF or LF flanges are either not available, or just not practical. Our universal 50.8 x 88.9mm (2×3.5”) rectangular flange, the Bulkhead D flange, accommodates standard 9, 15, 25 or 50 pin subminiature-D feedthroughs, and shares the same gasket and fastening accessories, providing simple and convenient interchangeability.

Custom flanges and cables are available, please contact our sales office for further details.

Features:
• 9 to 50 pin standard configuration.
• HV compatible construction.
• Kapton® & Teflon® insulated in-vacuum cables.
• Air & vacuum side connectors available.

1 - Please see catalogue section introduction for safety information. Stated electrical ratings are maximum test values. 
Feedthroughs are intended for instrumentation applications carrying low level signal voltages and currents.
2 - Assembly rating is reduced to that of the lowest rated component.
3 - DAP is a glass-filled dyiathilate.
