Overview
The Amphenol 71-490003-03P is a circular connector plug assembly designed for high-reliability applications. It features a shell size of 25 and utilizes a CA bayonet coupling mechanism for secure attachment. The contact arrangement includes one pin, specifically designated as contact number 1, which is configured with a crimp termination method to ensure robust electrical connections. This component is constructed using aluminum alloy for the shell material, providing necessary structural integrity while managing weight. The contacts are plated with gold over nickel to enhance conductivity and corrosion resistance in demanding environments.
Feature Summary
- Utilizes a CA bayonet coupling system for rapid and secure mating.
Applications
- Avionics systems requiring reliable signal transmission
- Ground support equipment interfaces
- Military communication hardware assemblies
Procurement Notes
Verify that the specific shell size and contact configuration match the design requirements before procurement. Ensure compatibility with the corresponding receptacle housing and cable preparation tools. Confirm that the environmental sealing characteristics meet the operational standards of the intended installation environment.
Selection Notes
Select this model when a single-pin connection with a bayonet lock is required. Consider the aluminum alloy construction for weight-sensitive applications. Validate that the crimp termination style aligns with available wiring harnesses and termination procedures.
Part Context
This part belongs to the Amphenol Series 71 family of circular connectors. These connectors are widely recognized in aerospace and defense sectors for their durability and standardized interface capabilities. The series offers various shell sizes and contact arrangements to accommodate different power and signal needs within complex electronic systems.
Replacement Considerations
Cross-reference with other manufacturers offering equivalent CA bayonet style connectors if supply chain constraints arise. Verify dimensional tolerances and contact plating specifications to ensure functional interchangeability without redesigning the mating interface.
