• Features a bayonet coupling system ensuring secure mechanical locking during operation
• Constructed with aluminum alloy housing for durability in harsh environments
• Designed for crimp termination to support reliable electrical signal transmission

Applications

• Avionics systems in military aircraft
• Ground-based radar equipment
• Communications infrastructure
• Test and measurement instrumentation

Procurement Notes

Verify the specific contact arrangement and shell finish against project requirements before procurement. Confirm that the crimp tooling matches the specified contact type. Ensure compatibility with mating plugs regarding the bayonet coupling interface. Check for any required accessory kits such as backshells or adapters. Validate that the component meets all applicable environmental qualification standards for the intended deployment.

Selection Notes

Select this model when a high-density circular connector is required for panel-mounted applications. The Series III designation indicates a composite body option availability, though this specific part uses metal housing. Consider the 14-position count for circuit density needs. Evaluate the bayonet lock speed against installation time constraints. Assess the environmental sealing capabilities if exposure to moisture or contaminants is expected.

Part Context

This component belongs to the extensive family of MIL-DTL-38999 connectors produced by Amphenol Aerospace. These connectors are widely recognized for their reliability in aerospace and defense sectors. The Series III variant offers increased contact density compared to earlier generations. The 71-series prefix typically denotes a specific manufacturer code within the broader standardization framework.

Replacement Considerations

Compatible replacements include other manufacturers' parts conforming to MIL-DTL-38999 Series III with shell size 14 and 14-14 insertion. Verify dimensional interchangeability and electrical ratings. Cross-reference with generic equivalents like MS27467 or similar designations if exact branding is not mandatory.
