71-528269-01S

Overview

The Amphenol Aerospace Operations model 71-528269-01S is a circular MIL-spec connector receptacle belonging to the 38999 series. It features a size 24 shell constructed from aluminum alloy and utilizes a crimp termination method for secure cable attachment. The component incorporates gold-plated copper contacts configured as sockets (female) within a straight, panel-mount arrangement. Designed for demanding environments, it meets MIL-DTL-38999 standards and provides reliable signal transmission with specified voltage ratings of 600 VAC and 850 VDC.

Feature Summary

• Constructed with an aluminum alloy shell for durability in harsh conditions
• Utilizes gold-plated copper socket contacts for reliable conductivity
• Features a straight panel-mount design for straightforward installation

Applications

• Avionics systems
• Aircraft control instrumentation
• Military communication equipment

Procurement Notes

Verify the specific manufacturer datasheet to confirm current availability and compliance with updated environmental regulations. Ensure that the crimping tools and mating connectors are compatible with the size 24 shell and contact configuration. Confirm that the straight mounting style aligns with the mechanical constraints of the intended panel interface before finalizing procurement orders.

Selection Notes

Select this component when a robust, MIL-DTL-38999 compliant circular connector is required for panel-mounted applications. The size 24 shell offers a balance of contact density and physical footprint suitable for avionics and military systems. The gold-plated contacts ensure low resistance and corrosion resistance, making it ideal for critical signal paths where reliability under vibration and temperature extremes is essential.

Part Context

This part belongs to the extensive portfolio of Amphenol Aerospace's 38999 series interconnect solutions. These connectors are widely recognized in the aerospace and defense sectors for their high performance and ruggedness. The 71-528269-01S specifically represents a standard receptacle variant, providing a foundational building block for complex wiring harnesses and electronic assemblies in commercial and military aircraft.

Replacement Considerations

Cross-reference with equivalent MIL-DTL-38999 Series III receptacles from other manufacturers if supply chain constraints exist. Verify that any substitute maintains the same size 24 shell, straight orientation, and crimp termination type to ensure mechanical and electrical compatibility without redesigning the host assembly.
