Product Listing


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.
