71-490002-98S

Overview

The Amphenol Aerospace Operations part number 71-490002-98S is a circular MIL-spec connector plug. It features a size 10 shell with a straight cable mount style and bayonet coupling mechanism. The connector utilizes a 10-98 insertion arrangement to accommodate six socket contacts. These contacts are constructed from copper alloy and feature gold plating for reliable signal transmission. The termination method specified is crimp, ensuring secure wire attachment. The housing is made of aluminum alloy with an olive drab cadmium finish to provide corrosion resistance in harsh environments.

Feature Summary

• Bayonet coupling mechanism provides rapid connection and secure locking
• Crimp termination ensures robust electrical connections for defined wire gauges
• Gold-plated copper alloy contacts offer high conductivity and corrosion resistance
• Aluminum alloy housing with protective coating supports rugged operational conditions

Applications

• Military ground combat vehicles
• Jet aircraft and helicopter avionics systems
• Naval surface ships and submarines

Procurement Notes

Verify the specific datasheet revision and contact current availability status directly with the manufacturer or authorized distributors. Confirm that the crimp tooling matches the contact specifications. Ensure environmental sealing requirements align with the intended installation location. Check for any specific handling precautions related to the bayonet coupling interface during assembly.

Selection Notes

Select this component when a size 10 circular plug with six positions is required for MIL-DTL-26482 applications. The straight cable mount design suits space-constrained enclosures where axial alignment is necessary. Verify that the operating environment temperature range and vibration levels are within the connector's rated capabilities. Ensure mating connectors share the same shell size and insertion arrangement for compatibility.

Part Context

This part belongs to the family of circular MIL-spec connectors designed for defense and aerospace sectors. It serves as a critical interconnect solution for transmitting power and signals in demanding operational scenarios. The design emphasizes durability and reliability under extreme mechanical and environmental stress conditions typical of military hardware deployments.

Replacement Considerations

Cross-reference with equivalent MIL-DTL-26482 series I connectors from other manufacturers. Verify dimensional compatibility and pinout configuration before substitution. Ensure the replacement part meets the same material and plating specifications to maintain performance integrity.
