Procurement Notes

Verify the exact mating counterpart specifications before procurement. Confirm that the receiving receptacle matches the shell size and contact arrangement. Ensure environmental sealing requirements align with the application's operational conditions. Cross-reference the manufacturer's latest datasheet for any design updates or compliance changes.

Selection Notes

Select this component when a threaded, cable-mount plug is required for MIL-DTL-5015 environments. Consider the current rating and contact material compatibility with the mating system. Evaluate the need for shielding effectiveness if electromagnetic interference protection is critical for the signal integrity of the connected circuitry.

Part Context

This part is part of the broader Amphenol PT series of circular connectors. These connectors are widely used in military and commercial aerospace sectors due to their rugged construction and standardized interface. The series offers various shell sizes and contact arrangements to accommodate different pin counts and current loads.

Replacement Considerations

Equivalent parts may include those from other manufacturers adhering to MIL-DTL-5015 standards. Verify dimensional interchangeability and electrical performance characteristics before substitution. Ensure that any replacement maintains the same thread type and engagement length.
