Subminiature-C (Sub-C, Type-C) - Ultrahigh (UHV), High Vacuum (HV), In-Vacuum
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 into a 1.33 inch CF metal seal and ISO-NW16KF elastomer seal vacuum flanges.
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 screw providing a means of securely locking connectors to a mating feedthrough. On the vacuum side, Kapton® insulated cable assemblies fitted with PEEK connectors are available to meet the rigorous demands of (UHV) ultrahigh vacuum as well as (HV) High Vacuum environments. In-vacuum connector screws are vented where required and the feedthrough's threaded-boss doubles as a connection polarizing key. Air to vacuum pin position is identified with a permanent surface mark, which clearly locates pin assignments. 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.

Subminiature-C (Sub-C, Type-C) - Ultrahigh (UHV), High Vacuum (HV), In-Vacuum
Accu-Glass Products Subminiature-C™ multipin hermetic feedthroughs (also known as Sub-C or Type-C multipin feedthroughs) are designed for applications where space is limited or where Subminiature-D (Sub-D) connections will not fit. This compact and unique 9-pin design allows installation into 1.33-inch CF metal seal and ISO NW16 KF elastomer seal vacuum flanges.
Nine gold-plated pins are arranged in a straight-through pin-to-pin design that are hermetically sealed and electrically insulated into a stainless-steel shell using the latest in glass-ceramic bonding technology.
Subminiature-C™ feedthroughs and cables are sold individually or as kits, where each kit contains a feedthrough with both vacuum and air side cable assemblies. Air and vacuum side connectors are fitted with captured stainless steel socket head screws that provide a secure means for locking them to their mating feedthroughs. On the vacuum side, Kapton® insulated cable assemblies fitted with PEEK connectors are available to meet the rigorous demands of (UHV) ultrahigh vacuum environments. In-vacuum connector locking screws are vented and where the feedthrough’s screw-boss also functions as a connection polarizing key. The air to vacuum 'pin-one' position is identified with a permanent surface mark for clear and simple pin assignment.
Warning: Please review 'Glow Discharge Graph' and how voltage rating is affected by pressure change.

| 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
- Unless designated a 'kit,' connectors and cable assemblies are not included with feedthrough and must be purchased separately.
