Our MIL-DTL-24308 compliant hermetic Sub-D DC connectors (.100" contact pitch) are compatible with lightweight materials like titanium and aluminum as well as conventional iron/nickel alloys. They are used in defense, space, and commercial applications where an extremely rugged and reliable hermetic seal is required due to harsh environmental conditions. The unique controlled CTE characteristics, chemical bonding properties and polycrystalline structure of Kryoflex®, allow the Hermetic Solutions Group to manufacture this connector with a 304L stainless steel or explosively welded Al/SS or Ti/SS shells and gold plated beryllium copper contacts for excellent electrical performance and environmental characteristics. These DC connectors can be produced for both laser-weld and solder-in housing applications.
