Overview
The Amphenol Aerospace Operations part number 71-418620-39X is a circular MIL-spec connector belonging to the MIL-DTL-38999 Series III family. It functions as a plug with a straight cable mount style and features a threaded coupling mechanism. The connector utilizes size 20 shell dimensions and provides 39 positions for socket-type contacts. These contacts are designed for crimp termination and are constructed from copper alloy materials with gold plating to ensure reliable signal transmission in demanding environments.
Feature Summary
- Threaded coupling design ensures secure connection integrity under vibration
- Gold-plated copper alloy contacts provide low resistance and corrosion resistance
- Crimp termination method supports robust wire attachment for durability
Applications
- Avionics systems requiring high-density interconnects
- Aircraft control and instrumentation circuits
- Harsh environment military communication equipment
Procurement Notes
Verify the specific suffix codes against official manufacturer documentation to confirm exact contact arrangements, shell material, and environmental sealing ratings. Ensure compatibility with mating receptacles within the same MIL-DTL-38999 series specifications before procurement.
Selection Notes
Select this component when a high-pin-count circular connector is required for space-constrained applications. The threaded interface offers superior retention compared to bayonet styles. Confirm that the crimp tooling matches the specified contact sizes for proper assembly.
Part Context
This part belongs to the extensive MIL-DTL-38999 Series III connector family produced by Amphenol Aerospace. These connectors are widely recognized for their compact size and high density relative to earlier generation MIL-C-26482 components. The series supports various shell materials and plating options to meet diverse operational requirements.
Replacement Considerations
Direct replacements include equivalent parts from other manufacturers adhering to MIL-DTL-38999 standards. Verify dimensional interchangeability and contact arrangement compatibility before substitution.
