Subminiature D

UHV 9, 15, 25, and 50-pin Subminiature-D hermetic feedthroughs 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.

UHV cable assemblies with PEEK connectors and Kapton® insulated ribbon cables are available to meet the demands of UHV environments.

The connection accessories must be purchased separately. Vacuum side cable assemblies, individual connectors and other accessories are detailed overleaf.

Custom subminiature D coaxial feedthrough products are available upon request.

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