MIL-DTL-38999 Connector Series III DLA QPL Environmental and Hermetic Connectors

D38999 Series III, the Industry Standard QPL Mil/Aero Connector Backed by Glenair Service and Availability

MIL-DTL-38999 Series III Connectors are the most widely specified connectors within the mil-aero industry — and for good reason. Developed for reliability, the MIL-DTL-38999 Connector Series III triple-start mating thread prevents galling and cross-threading while providing quick disconnect (single-turn action) to engage self-locking, grounded, metal-to-metal coupling. The Series III features accessory threads and environmental sealing for reliable attachment of backshells. The scoop-proof shell design protects crimp-removable contacts from damage. Integrated plug-to-receptacle grounding and shell-to-shell bottoming delivers 65dB minimum shielding at 10 GHz. A wide range of contact sizes, supported wire and insert arrangements IAW MIL-STD-1560 are available.

Contact Arrangement G29

Glenair is now a qualified supplier of the MIL-STD-1560 G29 contact arrangement.

MIL-DTL-38999 Series III Hermetic Connectors

Hermetic-class MIL-DTL-38999 Series III connectors are also available from Glenair with DLA certification. These hermetically sealed connectors are ideally suited for harsh environments where the environment exists under vacuum and must remain free of air or gas impurities via the ingress of foreign chemical substances. Such systems may be susceptible to the condensation of corrosive material, dielectric breakdown and the loss of insulation resistance between conductors. Typical applications include medical, geophysical, military aerospace and other industrial applications. Marked with D38999 or Glenair COTS part numbering, these hermetic class receptacles are available for MIL-DTL-38999 Connector Series III and IV in box mount, jam-nut, solder mount and weld mount shell styles. All standard material and finish classes are supported including Y (CRES, passivated) and N (CRES, electrodeposited nickel). Contact arrangements per MIL-STD-1560. All standard and normal and alternate key and keyway polarizations are fully supported. Best of all, defense and commercial aerospace customers, as well as land and marine engineers and procurement specialists may specify these mission-critical MIL-DTL-38999 interconnects directly from Glenair — the recognized service, support, and availability leader for the interconnect industry.
