71-418620-35W

Overview

The Amphenol Aerospace Operations part number 71-418620-35W is a circular MIL-spec connector plug belonging to the MIL-DTL-38999 Series III family. It features a shell size of 20 and utilizes a 35-position insertion arrangement with pin-type contacts. The connector employs a crimp termination method for secure wire attachment and is designed for cable mounting applications. Constructed from aluminum alloy, the housing provides durability for demanding environments. This component serves as a mating interface within high-reliability interconnect systems.

Feature Summary

• Threaded coupling mechanism ensures secure connection integrity
• Crimp termination style supports reliable wire attachment
• Aluminum alloy housing offers structural strength

Applications

• Avionics systems in commercial aerospace platforms
• Aircraft airframe power distribution networks
• Controls and instrumentation circuitry

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm exact contact plating, environmental sealing ratings, and mating compatibility. Ensure that the selected variant aligns with the required MIL-DTL-38999 performance standards for the intended operational environment. Cross-reference the insertion arrangement details to guarantee proper pin configuration matching.

Selection Notes

Select this component based on the requirement for a 20-shell size circular connector with 35 positions. Confirm that the crimp termination type matches the available wiring harness specifications. Evaluate the need for aluminum construction versus other materials based on weight constraints and corrosion resistance requirements for the specific installation location.

Part Context

This part belongs to the extensive MIL-DTL-38999 Series III product line offered by Amphenol Aerospace.
