Ceramaseal NOW has newly designed Sub D Type (MIL-C-24308 Type) connectors. The new Sub D Type connector is available as a 9-pin, 15-pin, 25-pin, and 50-pin connector. All of these standard connectors have gold-plated stainless steel conductors to maximize electrical characteristics. Ceramaseal offers these Sub D Type connectors as weldable units or flanged (ConFlat or ISO Flange) units. The new more rugged design fits industry standard screw type plugs and is much more weld friendly. These standard instrumentation Sub D Type connectors are rated for temperatures between –269°C to 450°C, DC voltages of 500 Volts per pin, current of 1 amp per pin, pressures up to 1,350 psig, and all of the connectors are non-magnetic. These connectors have ultra-high vacuum leak ratings of less than 1 x 10-10 atm cc/sec helium, as do all of Ceramaseal's standard feedthroughs and connectors.

Ceramaseal also offers the air-side and vacuum-side plugs for these multipin connectors. The vacuum-side plugs are manufactured using a polyketone insulating material. Also included in the Ceramaseal product offering is an in-vacuum ribbon cable for making the in-vacuum connection to the Sub D Type connectors. This is a flat polyimide-based cable that is completely flexible and vacuum compatible. The standard ribbon cable can withstand temperatures up to 200°C short term (150°C continuous) and current up to 1 amp per pin/line. Ribbon cables with a higher current carrying capacity are available upon request.

As always, Ceramaseal's team of engineers can CUSTOM DESIGN a solution for your demanding application. Putting multiple Sub D Type connectors in a flange is very common, as well as adding coaxial lines to the Sub D configuration.
