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.

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.
