• Threaded coupling design ensures secure mating and environmental sealing
• Crimp termination provides reliable electrical connections for wire harnesses
• Constructed from aluminum alloy housing for durability and weight efficiency

Applications

• Avionics systems in commercial and military aircraft
• Radar and communication equipment installations
• Harsh environment industrial control panels

Procurement Notes

Verify the specific shell size, contact arrangement, and plating finish against the engineering drawing before procurement. Confirm that the crimp tooling matches the specified contact size requirements. Ensure compliance with project-specific material certifications and traceability standards required for aerospace assembly processes.

Selection Notes

Select this connector when a high-density circular interface is required within the MIL-DTL-38999 Series I form factor. Evaluate the available contact configurations to ensure the 41-pin layout meets circuit density needs. Consider the operating temperature range and environmental sealing requirements typical of the JT series for suitable installation contexts.

Part Context

This component is part of the extensive Amphenol Aerospace circular connector portfolio, adhering to strict military specifications for performance consistency. The 71-series designation typically indicates a standard configuration within the broader JT product line, offering interchangeability with other manufacturers' parts meeting the same MIL-DTL-38999 standards.

Replacement Considerations

Equivalent parts from other manufacturers must meet MIL-DTL-38999 Series I specifications. Verify dimensional compatibility, including panel cutout dimensions and mounting hole patterns. Ensure contact current ratings and insulation resistance values match or exceed original design parameters.
