71-419579-19S

Overview

The Amphenol Aerospace Operations part number 71-419579-19S is a circular connector plug belonging to the PT series. It features a size 14 shell with a 19-position socket contact arrangement. The component utilizes crimp termination for cable attachment and is designed for panel mount installation. This connector is constructed from aluminum alloy housing with an electroless nickel surface finish, providing environmental sealing capabilities suitable for demanding operational conditions.

Feature Summary

• Self-locking threaded coupling mechanism ensures secure connection integrity
• Electroless nickel plated aluminum housing provides corrosion resistance
• Crimp termination method supports reliable electrical contact stability

Applications

• Commercial aerospace avionics systems
• Aircraft airframe power distribution
• In-flight entertainment control interfaces

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact contact configuration and plating specifications. Ensure compatibility with mating receptacles regarding shell size and thread type. Confirm that the crimp tooling matches the designated contact size requirements for proper assembly and performance validation.

Selection Notes

Select this component when a self-locking circular connector is required for commercial aerospace applications. Evaluate the need for electroless nickel plating versus other finishes based on environmental exposure. Verify that the panel mount style aligns with the chassis design constraints and that the crimp termination method fits the available assembly infrastructure.

Part Context

This part belongs to the PT series of circular connectors manufactured by Amphenol Aerospace Operations. The series is widely utilized in commercial aerospace environments where weight reduction and simplified installation are critical. These connectors are engineered to operate reliably in harsh conditions while supporting signal and low current distribution needs within aircraft systems.

Replacement Considerations

Cross-reference with equivalent MIL-DTL-38999 Series III connectors if military specification compliance is required. Verify dimensional interchangeability with existing mounting panels and mating interface geometries before substitution.
