71-419581-32S

Overview

The Amphenol Aerospace Operations part number 71-419581-32S is a circular connector plug belonging to the MIL-DTL-38999 Series III family. It features a straight cable mount design with a self-locking coupling mechanism. The housing is constructed from aluminum alloy and finished with electroless nickel plating. This component utilizes size 32 contacts arranged in a 32-position configuration, specifically designed for socket (female) mating interfaces. The termination method for the contacts is crimping, ensuring secure wire attachment. The unit is rated for operation within a temperature range of -65°C to +200°C and provides shielding against electromagnetic interference.

Feature Summary

• Self-locking bayonet coupling system for rapid connection and secure retention
• Electroless nickel plated aluminum shell for corrosion resistance
• Shielded construction for effective electromagnetic interference protection
• Crimp termination interface for reliable electrical contact

Applications

• Military avionics systems requiring MIL-DTL-38999 compliance
• Aerospace ground support equipment interconnects
• Harsh environment industrial control panels
• Defense communication hardware assemblies

Procurement Notes

Verify the specific suffix codes against the manufacturer's current datasheet to ensure compatibility with required contact arrangements and environmental seals. Confirm that the ordering designation matches the exact shell size and contact type specifications needed for your assembly. Cross-reference the revision level of the MIL-DTL-38999 standard applicable to your procurement requirements to guarantee regulatory adherence.

Selection Notes

Select this component when a shielded, self-locking plug is required for high-reliability applications. Ensure the mating receptacle shares the same shell size and contact arrangement. Verify that the crimp tooling available supports the specific contact sizes defined in the series documentation. Consider the operating temperature range and environmental sealing needs when finalizing the connector choice for the specific installation site.

Part Context

This part belongs to the extensive Tri-Start TV series of circular connectors manufactured by Amphenol Aerospace. These connectors are widely recognized in the defense and aerospace sectors for their rugged performance and standardized dimensions. The series offers various shell sizes and contact configurations to meet diverse wiring density requirements while maintaining strict military specification standards for durability and signal integrity.

Replacement Considerations

Compatible substitutes include equivalent MIL-DTL-38999 Series III plugs from other qualified manufacturers such as Glenair or ITT Cannon. Ensure any replacement maintains the identical shell size, contact arrangement, and coupling style. Verify that the substitute part meets the same environmental and electrical performance criteria specified in the original design documentation.
