Junior-D Connectors

The Hermetic Solution Group’s family of hermetic Junior-D connectors (.030″ 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 an absolute requirement. These Junior-D connectors, that incorporate the unique controlled CTE characteristics, chemical bonding properties and polycrystalline structure of Kryoflex® allow the Hermetic Solutions Group to manufacture this part with  aluminum, titanium or 304L stainless steel 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 applications.The Hermetic Solutions Group’s Junior-D connectors are much smaller version of our Mil-Spec Sub-D hermetic connectors and provide a space savings of approximately 70% over a standard Sub-D hermetic connector.
