Military QPL and Commercial Connectors for Harsh Environment Air-Tight-Seal Applications
Hermetic connectors are designed for use in harsh application environments. Sensitive photographic, sensor and surveillance equipment mounted in the tactical Unmanned Aerial Vehicle for example, must be able to operate in severe weather conditions, at high altitudes, under extremes of atmospheric pressure and in rapidly changing temperature gradients. Hermetic connector devices interconnecting the vacuum sealed black box equipment are selected for their ability to protect the controlled equipment environment by maintaining an air-tight seal between severe flight conditions and aircraft's sensitive payload.
Hermetic connectors are specified for applications as divergent as submarines and orbiting satellites. They are deployed to resist moisture ingress in underground applications and to withstand pressure differentials in vacuum chambers, laboratory equipment and commercial and military aircraft. Hermetic connectors, such as the MIL-DTL-38999 Series I, II, III and IV supplied by Glenair, are principally designed for use in military aerospace—in fact, the requirement for connector hermeticity was originally driven by military electronic applications. But the products are equally at home in commercial applications such as oil-patch, logging equipment or medical devices.
