71-432597-41P

Overview

The Amphenol Aerospace Operations 71-432597-41P is a circular MIL-spec connector receptacle designed for panel mounting. It features a jam nut installation style and utilizes a bayonet coupling mechanism for secure engagement. The component contains 41 positions with male pin contacts, arranged in the 22-41 insert configuration. Constructed from aluminum alloy with a nickel electroless plating, it ensures durability in harsh environments. The contacts are gold-plated copper alloy, supporting crimp termination for wire gauges ranging from 20 AWG to 16 AWG. Rated for 600 V and currents up to 13 A, it complies with MIL-DTL-26482 Series II standards.

Feature Summary

• Bayonet coupling system provides rapid and secure mating cycles
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Aluminum housing with nickel plating offers corrosion resistance
• Crimp termination supports robust wire gauge connections

Applications

• Avionics systems
• Military communication equipment
• Industrial instrumentation
• Radar systems

Procurement Notes

Verify that the specific ordering suffix matches the required contact arrangement and shell size. Confirm compliance with MIL-DTL-26482 Series II environmental requirements. Ensure the crimp tooling is compatible with the specified 20-16 AWG wire range. Check for RoHS status if applicable to the project constraints. Validate the jam nut mounting style against panel thickness specifications.

Selection Notes

Select this component when a 41-position circular connector is required for high-reliability applications. The bayonet lock is suitable for frequent connection cycles. Consider the 600 V rating and 13 A current capacity for power distribution needs. The aluminum construction balances weight and strength for aerospace use. Verify compatibility with existing MIL-DTL-26482 Series II mating interfaces.

Part Context

This part belongs to the MIL-DTL-26482 Series II family of miniature cylindrical connectors. These connectors are widely used in defense and aerospace sectors for their rugged performance. The series offers various shell sizes and contact arrangements to meet diverse wiring density requirements. Amphenol Aerospace manufactures these components to strict military specifications.

Replacement Considerations

Compatible substitutes include MS3474L22-41P and MS3120F22-41P. Verify that alternative parts match the 41-position count and bayonet coupling style. Ensure the replacement maintains the same MIL-DTL-26482 Series II compliance. Cross-reference the insert arrangement and wire gauge compatibility before substitution.
