71-418618-68S

Overview

The Amphenol Aerospace Operations 71-418618-68S is a circular MIL-spec connector plug designed for high-reliability applications. It features an aluminum shell in size 18 with a straight orientation and reverse bayonet coupling mechanism. The connector provides 8 positions utilizing gold-plated copper alloy contacts rated for crimp termination. Electrical specifications include a current rating of 13 A, with voltage ratings of 600 VAC and 850 VDC. Operating temperatures range from -55°C to 125°C.

Feature Summary

• Reverse bayonet coupling system ensures secure connection and rapid engagement.

Applications

• Aerospace avionics systems
• Defense electronic equipment
• Harsh environment interconnects

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm contact plating and environmental sealing requirements. Ensure compatibility with mating receptacles regarding shell size and coupling style. Confirm that the reverse bayonet interface matches the system design constraints before procurement.

Selection Notes

Select this component when a robust MIL-DTL-38999 Series I connector is required with a reverse bayonet lock. Consider the aluminum housing for weight-sensitive applications and verify that the 13 A current rating meets circuit demands. Ensure the crimp termination method aligns with available assembly tooling.

Part Context

This part belongs to the Amphenol 71 series, which corresponds to the MIL-DTL-38999 standard. It represents a legacy designation often cross-referenced with JT06RE series parts. The product line focuses on providing durable interconnect solutions for military and aerospace sectors requiring high cycle life and environmental resistance.

Replacement Considerations

Equivalent parts may include JT06RE-18-68S or MS3106E18-68S. Verify that substitute components maintain the reverse bayonet coupling and identical pin-out configuration to ensure mechanical and electrical interchangeability without redesign.
