- Bayonet coupling system ensures rapid and secure mating
- Aluminum alloy housing provides structural durability
- Electroless nickel plating offers environmental protection
Applications
- Aerospace avionics systems
- Military communication equipment
- Radar signal distribution networks
Procurement Notes
Verify the specific datasheet revision and compliance documentation before procurement. Confirm that the electroless nickel finish meets project environmental requirements. Ensure mating connectors share the same shell size and contact arrangement specifications to guarantee mechanical fit and electrical continuity in final assembly.
Selection Notes
Select this component when a 55-position MIL-DTL-38999 Series II plug is required. Verify that the application environment is compatible with aluminum housings and electroless nickel finishes. Ensure cable preparation tools support the specified crimp termination method for reliable performance under vibration and thermal cycling conditions.
Part Context
This part belongs to the extensive family of circular connectors manufactured by Amphenol Aerospace Operations. It serves as a critical interconnect solution within larger wiring harness assemblies. The designation links directly to legacy part numbers such as 71-482353-55S, maintaining backward compatibility with existing infrastructure designs requiring standardized military-grade connectivity.
Replacement Considerations
Cross-reference with MS27484E22-55S or equivalent MIL-DTL-38999 Series II plugs. Verify interface dimensions and contact arrangements match exactly. Ensure substitute parts maintain identical shell size and coupling style for direct replacement without modification.
