Hermetic Junior-DTM Connectors (.030″ Contact Pitch)

PA&E’s family of  hermetic Junior-D connectors are compatible with lightweight materials such as aluminum and titanium, as well as conventional iron/nickel alloys. They are designed for use in military, space, and commercial applications where environmental conditions require an extremely rugged and reliable hermetic seal. The Junior-D connectors DC connectors feature unique controlled CTE characteristics, chemical bonding properties and polycrystalline structure of Kryoflex,® allow PA&E to manufacture this part with a 304L stainless steel shell and gold-plated beryllium-copper contacts for excellent electrical performance and environmental characteristics. These DC connectors can be produced for both laser-welded and solder-in applications.

PA&E’s hermetic Junior-D connectors are a miniature version of our mil-spec Sub-D hermetic connectors and provide a space savings of 70% over a standard Sub-D.
