71-432198-41S

Overview

The Amphenol Aerospace Operations 71-432198-41S is a circular MIL-spec receptacle designed for panel mounting. It features a jam nut installation style and utilizes a bayonet coupling mechanism for secure engagement. The connector housing is constructed from aluminum with a nickel plating finish. Internal contacts are made of copper alloy and feature gold plating to ensure reliable signal transmission. This component supports crimp termination methods for wire connections.

Feature Summary

• Bayonet locking system for rapid connection and disconnection
• Panel-mount configuration with jam nut securing method
• Gold-plated copper alloy contacts for conductivity
• Aluminum shell with protective nickel coating

Applications

• Avionics systems in military aircraft
• Radar equipment interconnections
• Missile guidance control units
• Naval communication arrays
• Ground vehicle electronic modules

Procurement Notes

Verify the specific series designation and environmental sealing requirements against the official datasheet before procurement. Confirm that the mating plug matches the bayonet interface type. Ensure the cable assembly termination method aligns with the specified crimp contact requirements. Check for any updated qualification standards or material compliance certificates required by your project specifications.

Selection Notes

Select this component when a robust circular connector with a bayonet lock is required for panel-mounted applications. Consider the aluminum housing weight and durability benefits over plastic alternatives. Evaluate the gold contact plating for corrosion resistance in harsh environments. Ensure the panel cutout dimensions accommodate the jam nut style securely.

Part Context

This part belongs to the family of miniature cylindrical connectors defined by MIL-DTL-26482 specifications. These connectors are engineered for high-density wiring in defense and aerospace sectors. The design prioritizes mechanical strength and electrical reliability under vibration and shock conditions typical in mobile platforms.

Replacement Considerations

Compatible substitutes include MS3122E22-41S and MS3108E22-41P counterparts from other manufacturers adhering to the same MIL-DTL-26482 Series I standards. Verify dimensional compatibility and pin-out arrangements before substitution.
