Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm exact shell finish, contact material specifications, and environmental sealing ratings. Ensure compatibility with existing receptacle housings and mating interface requirements before procurement.

Selection Notes

Select this component when a ruggedized circular connector with bayonet coupling is required. Confirm that the five-position layout matches the circuit design. Verify that the operating environment falls within the specified temperature limits and that the crimp termination method aligns with available wiring tools.

Part Context

This part belongs to the PT series of miniature cylindrical connectors. These components are widely used in defense and aerospace sectors due to their durability and standardized dimensions. The series provides a robust solution for harsh environments where vibration and moisture resistance are critical operational factors.

Replacement Considerations

Cross-reference with MS3124E14-5P or similar MIL-DTL-26482 Series I equivalents. Verify dimensional tolerances and contact alignment to ensure direct interchangeability without modifying mounting brackets or cable assemblies.

FAQ

What is the coupling mechanism type?

The connector uses a bayonet coupling mechanism.

Is the connector shielded?
