Standard environmental-class MIL-DTL-38999 Series III connectors with DLA certification are now manufactured and supplied by Glenair. These industry standard connectors are ideally suited for a broad range of harsh environmental land, sea, air and space applications.
Marked with D38999 or Glenair COTS part numbering, these environmental crimp-contact connectors are available in cable plug or mounted jam nut / square flange receptacle shell styles. All standard material and finish classes are supported, including W (Cad/O.D. over electroless nickel), F (electroless nickel) and G (space-grade electroless nickel). RoHS-compliant finishes including Glenair MT (nickel-PTFE) and ZR (black zinc-nickel) are also available.
Contact arrangements per MIL-STD-1560 and all standard and normal and alternate polarisations are fully supported. To ensure electromagnetic compatibility (EMC), metal-to-metal coupling, plug grounding fingers and conductive shell finishes deliver excellent shielding performance up to 65 dB at 10 GHz.
The connectors’ scoop-proof design prevents inadvertent damage to pin contacts during mating, while interfacial and wire grommet seals deliver IP67 level sealing, even at high altitude. Triple-start stub ACME threads provide fast mating and resist galling and cross-threading. Contacts from size #22D signal to #12 shielded coax are supported.
