71-430582-27S

Overview

The Amphenol Aerospace Operations part number 71-430582-27S is a circular MIL-spec connector plug. It features a size 20 shell with a straight orientation and utilizes a self-locking coupling mechanism for secure attachment. The connector accommodates 14 positions configured as socket contacts, designed for crimp termination to ensure reliable electrical connections. Constructed with an aluminum alloy housing finished in nickel plating, it provides durability against environmental factors. This component complies with the MIL-DTL-5015 series standards, ensuring suitability for demanding aerospace and military applications requiring robust interconnect solutions.

Feature Summary

• Self-locking coupling system ensures secure mating without external tools
• Crimp termination method supports reliable wire-to-board connections
• Aluminum alloy housing with nickel plating offers corrosion resistance

Applications

• Aerospace avionics systems
• Military communication equipment
• Ruggedized industrial control panels

Procurement Notes

Verify the specific revision level of the MIL-DTL-5015 standard applicable to this order. Confirm that the crimp tooling matches the contact specifications for size 20 sockets. Ensure compatibility with corresponding receptacles featuring matching insertion arrangements. Check for any required environmental sealing accessories if operating in harsh conditions. Validate that the self-locking mechanism meets the torque requirements of the assembly design.

Selection Notes

Select this model when a straight cable entry is required for size 20 MIL connectors. The self-locking feature distinguishes it from threaded variants, offering faster connection cycles. Verify that the 14-position layout aligns with the circuit diagram requirements. Consider the aluminum housing weight constraints compared to stainless steel alternatives. Ensure the nickel finish is compatible with the intended electromagnetic interference shielding strategy.

Part Context

This part belongs to the extensive family of MIL-DTL-5015 circular connectors manufactured by Amphenol Aerospace. These connectors are widely recognized for their interchangeability and reliability in critical defense and aerospace sectors. The 71-series designation typically indicates a specific manufacturer's internal coding within the broader MIL-Spec framework, often corresponding to standard shell styles and contact arrangements defined by the governing military specification documents.

Replacement Considerations

Cross-reference with MS3459L20-27S or similar MIL-DTL-5015 plugs. Verify dimensional compatibility with existing panel cutouts and mating receptacles. Ensure equivalent current ratings and environmental sealing capabilities are maintained during substitution.
