71-418620-01F

Overview

The Amphenol Aerospace 71-418620-01F is a circular MIL-spec connector receptacle designed for wall mount installation. It features 41 positions with male pin contacts and utilizes a crimp termination style. The component adheres to the MIL-DTL-38999 II standard, ensuring compatibility with rigorous military specifications. Constructed with an aluminum shell size 20, it employs a bayonet coupling mechanism for secure engagement. The contacts are gold-plated to enhance conductivity and corrosion resistance, while the shell receives a nickel plating for environmental protection.

Feature Summary

• Bayonet coupling mechanism provides rapid and secure mating cycles
• Gold-plated contacts ensure reliable signal transmission in demanding environments
• Aluminum alloy shell offers structural integrity with reduced weight
• Wall mount configuration facilitates direct panel integration

Applications

• Avionics systems requiring MIL-DTL-38999 compliance
• Military ground vehicle electronic interconnects
• Maritime communication equipment installations
• Radar system signal distribution panels

Procurement Notes

Verify the specific suffix codes against the manufacturer's current datasheet to confirm exact contact arrangements and plating specifications. Ensure that the mating plug corresponds to the correct shell size and coupling type. Cross-reference the insertion arrangement number with the intended wiring diagram to prevent pinout mismatches during assembly.

Selection Notes

Select this component when a high-density circular connector is required for wall-mounted applications. The 41-position capacity supports complex signal routing within a compact form factor. Consider the bayonet coupling for applications requiring frequent connection cycles. Verify environmental sealing requirements, as the receptacle itself may require a seal or backshell for full ingress protection.

Part Context

This part belongs to the extensive family of circular connectors manufactured by Amphenol Aerospace. It falls under the MIL-DTL-38999 series, which is widely adopted across defense and aerospace sectors. The numbering convention indicates its position within the standardized interface definitions used for interoperability between different manufacturers' components.

Replacement Considerations

Compatible substitutes include MS27497E20F41PA and 91-542237-41E, which share identical dimensional and electrical characteristics. Ensure that any replacement maintains the same shell size, contact count, and coupling style to preserve mechanical fit.
