71-490006-32S

Overview

The Amphenol Aerospace Operations part number 71-490006-32S is a circular MIL-spec connector plug. It belongs to the PT series, specifically designated as PT05CE-18-32S(LC). This component is designed for secure electrical interconnections in demanding environments. The connector features a robust construction suitable for military and aerospace applications. It utilizes a size 18 shell and size 32 contacts. The LC suffix indicates specific locking or contact characteristics defined by the manufacturer.

Feature Summary

• Circular MIL-spec connector design for ruggedized interconnects
• Plug configuration with size 18 shell and size 32 contacts
• Suitable for high-reliability military and aerospace applications

Applications

• Military ground vehicles
• Naval ship systems
• Avionics equipment

Procurement Notes

Verify the exact mating counterpart and cable assembly requirements before procurement. Confirm that the LC designation aligns with system interface specifications. Ensure environmental sealing ratings meet operational standards. Cross-reference the manufacturer datasheet for precise pinout and termination details to guarantee compatibility with existing infrastructure.

Selection Notes

Select this component when a circular MIL-spec plug is required for size 18 shells. Consider the PT series for established reliability in defense sectors. Evaluate the LC variant against alternative locking mechanisms if vibration resistance is critical. Ensure the size 32 contact configuration matches the signal or power distribution needs of the target application circuitry.

Part Context

This part falls under the Amphenol Aerospace PT series of circular connectors. These connectors are widely used in defense and aerospace industries due to their durability and standardized interfaces. The 71-490006-32S identifier links directly to the PT05CE-18-32S(LC) product line, ensuring consistency with other components in the same family for system integration.

Replacement Considerations

The alphanumeric code 10-256040-71P is listed as an alias for a different Amphenol part (QWLD00R40N71P), which is a receptacle, not a plug. Therefore, it is not a direct functional substitute for this plug. Verify cross-compatibility with other PT-series plugs from Amphenol or equivalent MIL-DTL-26482 connectors only after confirming mechanical and electrical pinout alignment.
