Subminiature Power-D
Subminiature Power-D Feedthroughs
Power hermetic Subminiature-D feedthroughs are power contact combinations constructed with pin arrangements designed to meet IEC 807-2 and DESC 85039 specifications.
Standard configurations include power pins in a single Subminiature-D shell. Straight through pins are hermetically sealed and electrically insulated in a stainless steel shell using the latest in glass-ceramic bonding technology. Ultrahigh vacuum cable assemblies with PEEK connectors and Kapton® insulated wires are available to meet the demands of UHV environments.

Notes |
- Electrical ratings are maximum test values, with vacuum side at ≤ 1x10-4 Torr. Feedthroughs are designed for high power applications.
- PEEK is a polyether ether ketone thermoplastic.
- Overall assembly ratings must be adjusted to that of its lowest rated component.
- Unless designated a 'kit,' connectors and cable assemblies are not included with feedthrough and must be purchased separately.
