71-490005-26P

Overview

The Amphenol Aerospace Operations part number 71-490005-26P is a circular MIL-DTL-26482 Series I connector. It functions as a plug with male pin contacts and utilizes a crimp termination method. The assembly features an aluminum alloy shell with a cadmium and chromate finish, providing environmental resistance. Designed for free-hanging installation, it employs a bayonet coupling mechanism. The component is rated for operation between -55°C and 125°C, ensuring reliability in demanding aerospace and military environments.

Feature Summary

• Bayonet locking mechanism ensures secure mating under vibration
• Crimp termination supports reliable electrical connections
• Environmental sealing protects against moisture and contaminants
• MIL-DTL-26482 Series I compliance guarantees rigorous quality standards

Applications

• Aerospace avionics systems
• Military communication equipment
• Industrial instrumentation
• Public transportation control systems

Procurement Notes

Verify the specific series designation (Series I vs II) to ensure compatibility with existing mating connectors. Confirm that the crimp tooling matches the contact size requirements. Check for any specific environmental coating variations required by the end application. Ensure the manufacturer documentation aligns with current military specifications. Validate the operating temperature range against system constraints.

Selection Notes

Select this connector when a robust, shielded-free circular interface is required for fixed or cable-mounted applications. The male pin configuration dictates mating with female receptacles. Consider the aluminum shell material for weight-sensitive designs. Evaluate the bayonet lock speed against manual handling requirements. Ensure the crimp termination capability fits the available wire gauge options.

Part Context

This component belongs to the PT series of miniature cylindrical connectors manufactured by Amphenol Aerospace Operations. These connectors are widely utilized in high-reliability sectors where standard commercial connectors fail. The part number structure indicates specific shell size and contact arrangement within the broader MIL-DTL-26482 family framework.

Replacement Considerations

Cross-reference with MS3126E16-26P for direct functional equivalence. Verify shell size and contact count match exactly. Ensure the mating interface geometry remains compatible with existing panel cutouts or cable assemblies before substitution.
