71-529706-11X

Overview

The Amphenol Aerospace Operations part number 71-529706-11X is a circular MIL-spec connector, specifically identified as the JT08RP-18-11SC(318). It is a cable-mount receptacle with a size 18 shell. The connector features 11 socket contacts arranged in configuration 11. It utilizes a bayonet coupling mechanism for secure mating. The contacts are gold-plated copper alloy, and the housing is constructed from aluminum with an olive drab cadmium finish. This component is designed for harsh environment applications requiring reliable signal transmission.

Feature Summary

• Bayonet coupling system ensures rapid and secure connection
• Gold-plated contacts provide corrosion resistance and low contact resistance
• Aluminum housing offers durability in harsh environments

Applications

• Avionics systems
• Military communication equipment
• Aerospace instrumentation

Procurement Notes

Verify the exact suffix (318) and shell size (18) against the original design specification to ensure compatibility with existing cable assemblies and panel cutouts. Confirm that the bayonet coupling style matches the mating plug requirements. Check for any specific environmental sealing or shielding requirements not explicitly detailed in standard catalog descriptions.

Selection Notes

Select this component when a size 18, 11-position socket receptacle with bayonet coupling is required. Ensure the mating environment supports the operating temperature range typical of MIL-DTL-38999 Series I connectors. Verify that the cable entry orientation and strain relief capabilities meet the installation constraints of the specific assembly.

Part Context

This part belongs to the JT08 series, which is a high-density circular connector family compliant with MIL-DTL-38999 standards. The series is widely used in aerospace and defense industries due to its robust construction and reliable performance under extreme conditions. The specific model represents a standard configuration within this extensive product line.

Replacement Considerations

Compatible replacements include other manufacturers' MIL-DTL-38999 Series I connectors with matching shell size 18, 11 positions, and bayonet coupling. Ensure equivalent material specifications and contact plating are maintained for interchangeability.
