71-418624-19R

Overview

The Amphenol Aerospace Operations model 71-418624-19R is a circular connector assembly designed for high-reliability aerospace and defense applications. This specific part number denotes a receptacle configuration featuring a robust metal shell, typically constructed from corrosion-resistant materials to withstand harsh environmental conditions. The connector utilizes a threaded coupling mechanism to ensure secure mating and vibration resistance. It supports multiple contact arrangements, allowing for versatile signal and power transmission in critical systems where durability and consistent electrical performance are paramount.

Feature Summary

• Engineered with a ruggedized metal housing for enhanced mechanical protection and environmental sealing against dust, moisture, and corrosive agents.
• Incorporates a precision-threaded coupling interface that provides reliable retention and maintains seal integrity under severe vibration and shock loads.
• Designed to accommodate various contact types within a standardized shell size, facilitating flexible integration into complex avionics and ground support equipment architectures.

Applications

• Avionics systems requiring durable interconnects for flight-critical data and power distribution
• Ground support equipment operating in extreme environmental conditions
• Military communication and radar systems needing high-shock resistance

Procurement Notes

Verify the exact shell size, insert arrangement, and contact type against the official datasheet before procurement. Ensure compatibility with mating connectors regarding thread direction and keying options. Confirm material specifications and plating requirements meet project environmental standards. Cross-reference the full part number to avoid confusion with similar series variants that may differ in mounting style or contact configuration.

Selection Notes

Select this component based on required shell size and contact density rather than generic series features. Evaluate environmental sealing needs against IP ratings specified in the technical documentation. Consider mounting constraints such as panel thickness and available space for the threaded nut. Validate that the chosen contact types match the current and voltage requirements of the specific circuit application without relying on general family assumptions.

Part Context

This part belongs to the MIL-DTL-38999 Series I compatible family of circular connectors, widely used in aerospace industries. The 71-series designation often relates to specific manufacturer adaptations or legacy designations within Amphenol's portfolio. These connectors are characterized by their small size and light weight compared to older military standards, offering high pin count capabilities in compact form factors suitable for modern avionics integration.

Replacement Considerations

Check for direct cross-reference numbers listed in official interchangeability guides. Verify that any substitute matches the shell size, thread type, and contact arrangement exactly. Ensure environmental sealing and vibration resistance ratings are equivalent or superior. Do not assume functional equivalence based solely on physical dimensions; consult engineering drawings for precise fitment verification.
