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.

Stated electrical ratings are maximum test values. Feedthroughs are intended for instrumentation applications carrying low level signal voltages and currents.

For proper heat dissipation a maximum of 20% of the pins on a feedthrough may carry the maximum current at any one time.

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.
