The MS27473 type connector plug mates with all MIL-DTL-38999 Series II receptacles. It features a quick-disconnect bayonet coupling for positive contact engagement. The DS05 features grounding fingers for additional RFI protection. A strain relief backshell is required, and a protective cover is recommended to protect the connector and contacts when it is not mated. The insert arrangement can be found in our D38999 Series II Catalog. The DS05 meets or exceeds D38999 / MIL-DTL-38999 / MIL-C-38999.
