Rack and Panel Connectors
The Hermetic Solutions Group’s rack and panel DC connectors are compatible with lightweight housing materials such as aluminum and titanium, as well as conventional iron/nickel alloys. These DC connectors are used in defense, space, and commercial applications where environmental conditions require a rugged and reliable hermetic seal. The unique controlled CTE characteristics, chemical bonding properties and polycrystalline structure of Kryoflex®, allow the Hermetic Solutions Group to manufacture this part with gold-plated beryllium-copper contacts for excellent electrical performance and environmental characteristics.
These hermetic rack & panel DC connectors are manufactured for laser weld and solder-in applications. The Hermetic Solutions Group’s hermetically-sealed rack & panel connectors exceed the requirements of MIL-DTL-28748.
