Subminiature D Type Feedthroughs

Multipin hermetic subminiature D type instrumentation feedthroughs are constructed with pin arrangements designed to meet Mil-C-24308 specifications.
9, 15, 25 & 50 gold plated pins are in a straight through pin-to-pin design and are hermetically sealed and electrically insulated in 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.

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 100 pin standard configuration.
• High temperature rated to 250°C.
• UHV compatible construction.
• Kapton® 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 - PEEK is a polyetheretherketone thermoplastic.
4 - DAP is a glass-filled dyiathilate.
