Hermetic Aluminum 38999 Connector from PA&E

Built to the same rugged standards as the company’s other robust, MIL-Spec compliant interconnect products, this new, connector combines PA&E’s patented Kryoflex ceramic-to-metal sealing technology, beryllium copper CDA alloy 172/173 contacts for superior electrical performance in a weight-saving all-aluminum shell.

“This new aluminum 38999 DC connector is unique in the market,” said Shaun McGuire, PhD, vice president of engineering at PA&E. “We can now offer our customers a 38999 connector that is up to 60% lighter than our standard stainless steel version and still provides the reliable hermetic performance we’re known for.”

PA&E’s new aluminum 38999 DC connector has an operating temperature range of -65°C to 155°C and a leak rate of less than 1X10-9 cc/sec helium at one atmospheric differential pressure. It provides insulation resistance of more than 5,000 megohms at 500 VDC during dielectric withstanding voltage testing and exhibits no evidence of breakdown or flashover when tested IAW MIL-STD-1344, Method 3003. The connector accepts 24 to 30 AWG solid or stranded wire.

The new aluminum circular 38999 hermetic connector from PA&E can be designed to be laser welded into aluminum housings. Laser welding is a non-contact, high-precision welding process that exhibits an extremely small heat-affected zone, ensuring components or electronic packages are exposed to the least-hostile welding environment possible. The connector is also available in a jam-nut style.

Besides this new aluminum-shell connector, PA&E custom manufactures circular and rectangular DC connectors in a number of configurations including options with standard stainless steel shells that use both Kryoflex ceramic-to-metal and glass-to-metal sealing processes.
