Hermetic Sub-D Connectors
Our family of MIL-DTL-24308 compliant hermetic Sub-D DC connectors (.100″ Contact Pitch) 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 unique controlled CTE characteristics, chemical bonding properties and polycrystalline structure of Kryoflex®, allow PacAero 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-welding and solder-in applications.
