71-418622-01X

Overview

The Amphenol Aerospace Operations model 71-418622-01X is a circular MIL-spec connector component belonging to the MS3106 series. It functions as a straight plug with a size 22 shell and features 41 positions for socket contacts. The unit utilizes a bayonet coupling style for secure attachment and employs crimp termination methods for wire connections. Constructed with aluminum alloy shells finished in cadmium plating, it supports copper alloy contacts plated with gold. This configuration ensures reliable electrical performance within defined environmental limits typical of military-grade interconnect systems.

Feature Summary

• Bayonet coupling mechanism provides rapid engagement and secure locking
• Crimp termination interface allows for robust wire-to-contact assembly
• Gold-plated copper alloy contacts ensure low contact resistance and corrosion resistance
• Aluminum alloy housing offers structural durability with protective surface treatment

Applications

• Military avionics systems requiring standardized interconnects
• Ground support equipment signal distribution
• Aerospace control panel wiring interfaces
• Radar system connection points

Procurement Notes

Verify the specific suffix designation against the manufacturer's current datasheet to confirm exact material specifications and plating requirements. Ensure compatibility with mating receptacles regarding shell size and contact arrangement. Confirm that the bayonet coupling style matches the receiving panel or cable assembly interface requirements before finalizing procurement orders.

Selection Notes

Select this component when a size 22 straight plug with 41 positions is required for high-density signal routing. Verify that the operating environment aligns with the temperature and humidity ratings specified in the official documentation. Ensure that the crimp tooling available matches the contact sizes supported by this shell configuration for proper assembly.

Part Context

This part belongs to the MS3106 series of circular connectors, which are widely used in defense and aerospace applications. The series defines standard dimensions and interface characteristics for interchangeable components from various manufacturers. The specific model number indicates the shell size, contact count, and coupling type within this standardized family framework.

Replacement Considerations

Cross-reference with other manufacturers offering MS3106-style connectors to verify dimensional interchangeability. Ensure that any substitute part maintains the same bayonet coupling style and contact arrangement to guarantee mechanical and electrical compatibility with existing mating hardware.
