Subminiature-C (Sub-C) NW ISO KF / LF Feedthroughs
Subminiature-C High Vacuum (HV) Feedthroughs
Accu-Glass Products Subminiature-C multi-pin hermetic feedthroughs (also known as Sub-C or Type-C) are designed for applications where space is limited, or where Subminiature-D (Sub-D) connections will not fit. Its compact design allows installation of one Subminiature-C 9-pin feedthrough into an ISO-NW16KF elastomer seal vacuum flange, or two (2) Subminiature-C 9-Pin feedthroughs on an ISO NW40 KF flange.
Nine gold-plated pins are arranged 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.
Air and vacuum side connectors are fitted with a captured stainless steel socket-head cap screw providing a means of securely locking connectors to the mating feedthrough. On the vacuum side, Kapton® insulated cable assemblies fitted with PEEK connectors are available to meet the rigorous demands of (HV) high vacuum environments. In-vacuum connector screws are vented where required and the feedthrough's threaded-boss doubles as a connection polarizing key. The air and vacuum Pin-1 position is identified with a permanent surface mark, facilitating and simplifying electrical lead and pin assignment. Subminiature-C feedthroughs and cables are sold individually or as kits, where each kit contains a feedthrough and both vacuum and air side cable assemblies.

| Notes |
- Electrical ratings are maximum test values, with feedthrough's vacuum side at ≤ 1x10-4 Torr. Feedthroughs are intended for instrumentation applications carrying low level signal voltage and current.
- For proper heat dissipation, a maximum of 20% of the pins on a feedthrough may carry the maximum pin current at any given time.
- PEEK is a polyether ether ketone thermoplastic.
- Leak tested to 5x10-10 Standard cc/sec of He.
- Overall assembly ratings must be adjusted to that of its lowest rated component. For cryogenic service, the lowest recommended temperature is -200°C (without elastomer gasket)
- Unless designated a 'kit,' connectors and cable assemblies are not included with feedthrough and must be purchased separately.
