71-528269-29P

Overview

The Amphenol Aerospace Operations part number 71-528269-29P is a circular MIL-spec connector receptacle belonging to the MS3470 series. It features an aluminum alloy shell with olive drab cadmium plating and utilizes a bayonet coupling mechanism for secure attachment. The unit contains 29 socket contacts arranged in a 24-29 insertion configuration, designed for crimp termination on copper alloy conductors. Electrical ratings include a current capacity of 11 amperes per contact and a voltage rating of 600 volts AC or DC. The connector operates within a temperature range of -55°C to +200°C and provides environmental sealing capabilities suitable for harsh aerospace and industrial conditions.

Feature Summary

• Bayonet coupling system ensures rapid connection and secure locking against vibration
• Aluminum alloy housing with corrosion-resistant surface treatment for durability
• Crimp termination interface supports reliable electrical connections for signal and power distribution
• Environmental sealing design protects internal contacts from moisture and contaminants

Applications

• Aerospace avionics systems requiring high reliability
• Military communication equipment interfaces
• Industrial control panel interconnections
• Ruggedized instrumentation signal routing

Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm exact contact arrangements and plating specifications. Ensure compatibility with mating plugs regarding shell size and keying options. Confirm that the crimp tooling matches the specified contact sizes for proper termination integrity. Check for any updated compliance certifications required by your procurement standards before finalizing orders.

Selection Notes

Select this component when a straight cable-mount receptacle with bayonet locking is required for MIL-DTL-26482 Series I applications. Consider the 29-position count and socket configuration for circuit density needs. Evaluate the operating temperature range and environmental sealing requirements against the application profile. Ensure the mating plug shares the same shell size and coupling style for proper assembly.

Part Context

This part belongs to the MS3470 series of miniature cylindrical connectors manufactured by Amphenol Aerospace. These connectors are designed to meet MIL-DTL-26482 Series I specifications, offering a compact form factor for space-constrained environments. The series is widely used in defense and aerospace sectors where vibration resistance and environmental protection are critical performance factors.

Replacement Considerations
