Procurement Notes

Verify the exact shell size and contact type compatibility with mating receptacles before procurement. Ensure that the crimp tooling matches the specific contact specifications required for this assembly. Confirm environmental sealing requirements if the application involves exposure to moisture or contaminants. Cross-reference the drawing numbers to guarantee mechanical fit within the designated enclosure.

Selection Notes

Select this component when a high-pin-count circular connector is needed for fixed installations. Evaluate the available shell sizes to ensure adequate space for the required number of contacts. Consider the termination style to match existing cable preparation processes. Assess the environmental protection level required by the specific operational context to determine if additional sealing measures are necessary beyond the standard connector design.

Part Context

This part belongs to the Amphenol Series 71 family of circular connectors, widely used in aerospace and defense sectors. The series is known for its MIL-DTL-38999 compliance and robust construction.
