71-482351-11S

Overview

The 71-482351-11S is a circular MIL-spec connector plug manufactured by Amphenol Aerospace Operations. It features a size 18 shell with an S coupling nut and bayonet lock mechanism. The assembly contains 11 socket contacts arranged in a 11-11 configuration. Contacts utilize crimp termination for wire attachment. The housing is constructed from aluminum alloy with electroless nickel plating. This component complies with MIL-DTL-38999 Series I standards, ensuring environmental sealing and robust performance for demanding operational conditions.

Feature Summary

• Bayonet locking coupling nut provides rapid connection and secure retention
• Aluminum alloy housing with electroless nickel finish ensures corrosion resistance
• Crimp contact termination supports reliable high-frequency signal transmission
• MIL-DTL-38999 Series I compliance guarantees environmental sealing integrity

Applications

• Avionics systems requiring compact circular interconnects
• Military ground vehicle electronic control units
• Aerospace instrumentation and sensor arrays
• Ruggedized communication equipment interfaces

Procurement Notes

Verify the specific suffix codes against official Amphenol documentation to confirm exact contact arrangement and plating specifications. Ensure compatibility with mating receptacles regarding shell size and thread type. Confirm that the crimp tooling matches the designated contact size for proper termination. Request current manufacturing status and lead times directly from authorized distributors or the manufacturer to align with project schedules.

Selection Notes

Select this model when a Series I circular connector with a bayonet lock is required for space-constrained applications. The size 18 shell offers a balance of pin count and form factor. Verify that the operating temperature range meets system requirements. Ensure the cable diameter accommodates the strain relief capabilities of the plug assembly. Cross-reference the 11-11 contact layout with the circuit diagram to prevent pinout mismatches during integration.

Part Context

This part belongs to the JT08RE series of circular connectors designed for military and aerospace environments. The JT08RE designation indicates a standard interface with environmental sealing capabilities. Amphenol Aerospace Operations produces these components to meet rigorous MIL-DTL-38999 specifications. The series is widely used in defense electronics where reliability under vibration and harsh conditions is critical.

Replacement Considerations

Equivalent parts include 1178-JT08RE-18-11S and 71-482351-11S variations from other qualified manufacturers. Verify cross-compatibility with existing panel cutouts and mating receptacles before substitution. Ensure that any replacement maintains the same MIL-DTL-38999 Series I certification and physical dimensions.
