It features an in-line cable mount design with a bayonet coupling mechanism. The housing size is 22, accommodating 4 positions configured as socket contacts. The unit utilizes crimp termination for wire attachment and gold-plated copper alloy contacts. Rated for 600 VAC and 7.5 A current, it operates within a temperature range of -65°C to 200°C. The aluminum shell provides nickel plating for environmental protection.

Feature Summary

• Bayonet locking mechanism ensures secure mating and vibration resistance
• Crimp termination supports reliable electrical connections
• Gold-plated contacts provide corrosion resistance
• In-line cable receptacle design facilitates direct wiring

Applications

• Avionics systems
• Military equipment
• Aerospace instrumentation

Procurement Notes

Verify the exact suffix against official Amphenol documentation to confirm contact arrangement and plating specifications. Ensure compatibility with corresponding MS3472 series plugs. Confirm RoHS status and material declarations with the manufacturer prior to procurement.

Selection Notes

Select this component for applications requiring a 4-position circular interface with high thermal stability. The in-line form factor suits cable-to-cable or cable-to-panel connections where space constraints favor a straight orientation. Verify that the mating plug shares the same shell size and contact configuration.

Part Context

This part belongs to the MS3471 series of miniature cylindrical connectors defined by MIL-DTL-26482 Series II. The series is characterized by its bayonet coupling and robust construction for harsh environments. Amphenol manufactures these connectors to meet stringent military standards for reliability and performance.

Replacement Considerations

Compatible substitutes include MS3471L22-41SW and other MS3471 variants with matching shell size 22 and 4-position socket arrangements. Verify pinout and mounting style equivalence before substitution.
