71-419749-19S

Overview

The Amphenol Aerospace Operations 71-419749-19S is a circular MIL-spec connector belonging to the PT series, manufactured under MIL-DTL-26482 Series I standards. This component functions as a straight plug with a bayonet coupling mechanism. It features an aluminum alloy shell finished in olive drab cadmium plating and contains 19 positions utilizing socket-type contacts. The contacts are constructed from copper alloy and feature gold plating for reliable signal transmission. Termination is achieved via crimping methods, and the unit is designed for cable mounting applications.

Feature Summary

• Bayonet locking mechanism ensures secure mating and quick connection
• Gold-plated copper alloy contacts provide corrosion resistance
• Olive drab cadmium plated aluminum shell offers environmental protection

Applications

• Aviation systems
• Military equipment
• Industrial instrumentation

Procurement Notes

Verify that the specific part number matches the required MIL-DTL-26482 Series I compliance and confirm the contact configuration aligns with system requirements. Ensure that the crimp termination method is compatible with the selected wire gauge and that the bayonet coupling style suits the installation environment. Cross-reference the manufacturer datasheet for precise dimensional tolerances and material certifications before finalizing procurement orders.

Selection Notes

Select this model when a straight plug configuration with a bayonet lock is required for MIL-DTL-26482 Series I environments. The 19-position count and socket contact type must match the mating receptacle specifications. Consider the crimp termination requirement and ensure the aluminum shell finish meets the necessary corrosion resistance standards for the intended operational conditions.

Part Context

This component is part of the PT series circular connectors produced by Amphenol Aerospace Operations. It adheres to the MIL-DTL-26482 Series I specification, which defines miniature cylindrical connectors for demanding applications. The series is characterized by its robust construction and standardized interface dimensions, ensuring interchangeability within the military specification framework.

Replacement Considerations

Compatible substitutes include MS3122E19-19S and MS3106E19-19S, provided they conform to the same MIL-DTL-26482 Series I standard and maintain identical shell size, position count, and coupling style.
