71-418620-02R

Overview

The Amphenol Aerospace Operations part number 71-418620-02R is a circular MIL-spec connector plug. It features 2 positions with pin (male) contacts. The shell size is 20, and the mounting style is cable. This component utilizes crimp termination for electrical connections. The series designation is MIL-DTL-38999, specifically Type III. The coupling mechanism is bayonet. The housing material is aluminum alloy. Contact plating is gold over nickel. The voltage rating is 500 VDC.

Feature Summary

• Bayonet coupling mechanism provides secure connection in demanding environments
• Aluminum alloy shell construction offers durability and weight efficiency
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Crimp termination supports robust cable assembly integration

Applications

• Aircraft avionics systems
• Airframe power distribution
• Control and instrumentation circuits
• Wire bundling and cable management

Procurement Notes

Verify the specific datasheet revision and environmental sealing requirements against the application needs. Confirm that the mating receptacle matches the bayonet coupling style and shell size. Ensure the contact arrangement aligns with the system wiring diagram. Check for any specific RoHS or compliance certifications required by the end-use industry standards before finalizing procurement.

Selection Notes

Select this component when a MIL-DTL-38999 Series III plug is required for panel or cable mounting. The 2-position configuration suits low-pin-count signal applications. Verify that the operating temperature range meets the environmental conditions. Ensure the crimp tooling is compatible with the specified contact sizes for proper termination quality.

Part Context

This part belongs to the MIL-DTL-38999 family of circular connectors, widely used in aerospace and defense. The 71-series prefix indicates an Amphenol industrial designation often cross-referenced with military standards. These connectors are designed for high-density interconnects in harsh environments requiring vibration resistance and reliable performance.

Replacement Considerations

Cross-reference with standard MIL-DTL-38999 Series III equivalents. Verify compatibility with mating receptacles from other manufacturers adhering to the same military specification. Ensure dimensional interchangeability for panel cutouts and cable entry points.
