71-482349-35S

Overview

The Amphenol Aerospace Operations 71-482349-35S is a circular MIL-spec connector plug designed for high-density interconnect applications. It features 128 positions with male pin contacts, utilizing a size 24 shell and straight cable mount configuration. The component complies with MIL-DTL-38999 Series II standards and employs a bayonet coupling mechanism for secure engagement. Contacts are gold-plated copper alloy, terminated via crimp connections to support wire gauges ranging from 20 AWG to 24 AWG. The aluminum alloy housing provides an olive drab cadmium finish for corrosion resistance in demanding environments.

Feature Summary

• High-density 128-position interconnect capability within a compact size 24 shell
• Bayonet coupling system ensures rapid and secure mating cycles
• Gold-plated contacts provide reliable signal transmission in harsh conditions
• Crimp termination supports flexible wiring configurations

Applications

• Avionics systems requiring high pin count connectivity
• Military ground vehicle electronic architectures
• Shipboard communication and radar equipment
• Industrial control panels in corrosive environments

Procurement Notes

Verify the specific suffix codes against the manufacturer's current datasheet to ensure compatibility with mating receptacles and environmental sealing requirements. Confirm that the bayonet coupling style matches the intended panel or cable assembly interface. Cross-reference the contact type and plating specifications with the application's electrical load and environmental exposure criteria before finalizing procurement orders.

Selection Notes

Select this model when a high-pin-count solution is required within strict spatial constraints defined by size 24 shells. Ensure the mating environment accommodates the bayonet coupling mechanism rather than threaded interfaces. Verify that the crimp termination method aligns with available tooling and wire gauge ranges specified for the 20-35 insertion arrangement.

Part Context

This part belongs to the Amphenol 38999 Aluminum series, representing a legacy designation often cross-referenced with MS27484 standards. It serves as a critical component in defense and aerospace sectors where reliability under vibration and extreme temperatures is mandatory. The design prioritizes mechanical durability and consistent electrical performance across extensive operational lifecycles.

Replacement Considerations

Equivalent parts include MS27484P24A35PC and other variants within the MIL-DTL-38999 Series II family. Ensure dimensional compatibility of the bayonet lock and identical pin/socket arrangements before substitution.
