Subminiature-C, the latest addition to a comprehensive line of glass-to-metal, hermetically sealed instrumentation feedthroughs. This is a circular geometry 9 pin feedthrough designed for applications where space is at a premium or where conventional Subminiature Type-D connections will not fit. Its circular geometry allows the installation of this product into very small vacuum flanges including the popular DN16CF and KF16 flanges. 9 gold plated pins are hermetically sealed and electrically insulated in a stainless steel shell using the latest in glass-ceramic bonding technology.

Each kit is supplied with both an air and vacuum-side cable assembly including connectors. Subminiature-C air and vacuum-side connectors are fitted with captured stainless steel socket head screws which provide a means of securely locking them to their mating feedthroughs. All in-vacuum connector screws are vented where required. The feedthroughs mating-screw boss doubles as a polarising key. Air to vacuum pin positions are identified with a permanent surface indentation to facilitate the pin assignment operation.

  • 9, 23, 37 and 60 pin instrumentation feedthroughs
  • UHV Compatible construction
  • Conflat® and KF mounting flanges
  • High temperature rated to 250°C maximum
  • Leak tight to 2 x 10-10 std. cc/sec of helium

Each cable assembly is fitted with a PEEK® Subminiature-C male or female connector. The female connector mates directly onto the vacuum-side of a 9 pin Subminiature-C feedthrough.
Caution – these cable assemblies do not include the PEEK® connector and they will not allow subsequent connector installation. Wires must be threaded through connector back piece before crimping contacts.
Contact fitted leads are individual wire strands and are not bundled cable. They are ideally suited for vacuum applications with multiple or complex wire routing requirements. These will allow subsequent connector installation.
All UHV cable assemblies are bakeable to 250°C. UHV connectors are made from PEEK® and wired with Kapton® insulated silver plated copper leads.
