71-477103-22S

Overview

The Amphenol Aerospace Operations 71-477103-22S is a circular MIL-spec plug connector designed for rugged military and aerospace applications. It belongs to the MS3471 series, complying with MIL-DTL-26482 II standards. The unit features a size 22 shell with a bayonet coupling mechanism and straight cable entry. It utilizes crimp termination for secure wire attachment and gold-plated copper alloy contacts to ensure reliable signal transmission in harsh environments.

Feature Summary

• Bayonet coupling system provides rapid connection and secure locking
• Crimp termination ensures durable electrical connections
• Gold-plated contacts offer corrosion resistance and conductivity

Applications

• Military ground vehicles
• Jet aircraft and helicopters
• Naval ships and submarines

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Confirm that the ordering suffix matches the required contact arrangement and plating specifications. Ensure compatibility with mating receptacles within the same MIL-DTL-26482 II family to guarantee proper interface performance.

Selection Notes

Select this component when a shielded, cable-entry plug is required for MIL-DTL-26482 II systems. The size 22 shell accommodates specific pin counts suitable for moderate channel density. Verify environmental sealing requirements and mating interface constraints against the application's mechanical and electrical needs.

Part Context

This part is manufactured by Amphenol Aerospace Operations, a provider of interconnect systems for defense and aerospace sectors. The 71-477103-22S falls under the broader category of circular MIL-spec connectors, specifically designed for high-reliability applications where vibration and environmental exposure are critical factors.

Replacement Considerations

Compatible substitutes include other manufacturers' parts conforming to MIL-DTL-26482 II with matching shell size 22 and bayonet coupling. Cross-reference pinout arrangements and contact types to ensure interchangeability without redesigning the mating assembly.
