Hermetic hermetic weld mount receptacles are specified where the connector body must hold vacuum or pressure in addition to carrying signal: airborne sensor pods, IR and EO gimbal electronics, fuel and hydraulic pressure bulkheads, satellite bus panels and instrument housings. The glass-fused insert gives a hermetically sealed interface capable of <1×10⁻¹⁰ cc He/s helium leak rate, and the connector mates with any standard MIL-DTL-38999 Series III plug of the same shell size and insert arrangement.
