71-477104-05P

Overview

The Amphenol Aerospace Operations part number 71-477104-05P is a circular connector component belonging to the MIL-DTL-26482 Series I or II family, specifically identified as a receptacle housing with male pin contacts. The alphanumeric suffix '14-5' indicates an shell size of 14 and a contact arrangement supporting 5 positions. This component is designed for panel mount installation using a flange interface and utilizes a pin lock fastening mechanism. It features crimp termination for wire connections and is constructed with a metal housing, typically aluminum alloy, finished with non-electrolytic nickel plating. The contacts are made from copper alloy with gold plating to ensure reliable electrical performance in demanding environments.

Feature Summary

• Military-grade construction compliant with MIL-DTL-26482 specifications for ruggedized interconnect applications
• Panel mount receptacle design with integrated flange for secure structural attachment
• Pin lock fastening system provides positive retention and vibration resistance
• Crimp termination method ensures durable mechanical and electrical connection to conductors

Applications

• Avionics systems in military aircraft and helicopters
• Naval ship surface and submarine communication equipment
• Ruggedized ground vehicle electronic control units
• Defense infrastructure signal processing modules

Procurement Notes

Verify that the specific revision level of the MIL-DTL-26482 standard matches your design requirements, as Series I and II have distinct dimensional differences. Confirm the presence of the LC (Lead Compatible) suffix if lead-free compliance is mandatory for your assembly process. Ensure the mating connector corresponds to the correct shell size and contact arrangement to guarantee proper alignment and engagement within the 14-5 configuration.

Selection Notes

Select this component when a robust, shielded-capable circular connector is required for panel mounting in harsh environments. The 14-5 arrangement suits applications needing five signal or power lines. Consider the operating temperature range and environmental sealing needs relative to the specific series variant. Evaluate the crimp tooling compatibility with the specified contact materials before finalizing the bill of materials.

Part Context

This part number falls under the extensive portfolio of Amphenol Aerospace's MIL-DTL-26482 connectors, which serve as a standard for lightweight, high-density interconnects in defense and aerospace sectors.
