Procurement Notes

Verify the specific contact arrangement and shell size against the official datasheet to ensure compatibility with mating connectors. Confirm that the crimp termination type matches the wire gauge requirements of the application. Check for any specific ordering suffixes that may alter material finishes or contact plating options. Ensure the supplier provides traceability documentation required for military and aerospace procurement standards.

Selection Notes

Select this component when a Series I interface is required with free-hanging mounting flexibility. Consider the thermal range up to 200°C for high-temperature environments. Evaluate the need for shielding in noisy electromagnetic settings. Compare against Series II or III variants if different mechanical interfaces or higher current capacities are needed for the specific system design.
