Procurement Notes

Verify the specific contact arrangement and gender against the official datasheet before procurement. Confirm that the bayonet locking style matches the mating plug requirements. Ensure the wall-mount orientation aligns with the chassis design constraints. Cross-reference the manufacturer part number with legacy equivalents if replacing existing infrastructure components.

Selection Notes

Select this component when a ruggedized circular connector with a bayonet lock is required for wall-mount applications. Consider the aluminum housing material for weight and corrosion resistance balance. Evaluate the available pin/socket configurations to match circuit density needs. Ensure compatibility with the operating environment's temperature and vibration specifications defined in the MIL-DTL-83723 standard.

Part Context

This connector belongs to the MIL-DTL-83723 family, which defines high-performance circular connectors for aerospace and defense. Amphenol Aerospace Operations produces this line to meet stringent military standards for reliability. The 71-series designation indicates a specific shell size and contact arrangement within the broader MIL-DTL-83723 ecosystem, ensuring interchangeability with other compliant manufacturers' parts where applicable.

Replacement Considerations

Check for cross-referenced part numbers from other MIL-DTL-83723 III qualified manufacturers. Verify dimensional compatibility for panel cutouts and mounting holes. Ensure electrical ratings and contact arrangements match the original system requirements.
