71-419749-12P

Overview

The Amphenol Aerospace Operations connector, identified by part number 71-419749-12P and series PT08CP, is a circular MIL-spec receptacle designed for panel installation. It features a size 14 shell with a jam nut mounting style and utilizes a bayonet coupling mechanism. The assembly contains 12 positions configured with male pin contacts that employ crimp termination methods. The housing is constructed from aluminum alloy and finished with cadmium plating treated with chromate conversion coating to ensure environmental durability.

Feature Summary

• Bayonet locking mechanism provides rapid engagement and secure retention
• Crimp termination ensures reliable electrical connection for wire harnesses
• Aluminum alloy housing offers structural integrity in harsh environments

Applications

• Military avionics systems requiring MIL-DTL-26482 compliance
• Radar and communication equipment interfaces
• Industrial control panels exposed to corrosive atmospheres

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm contact material and plating specifications. Ensure the crimp tooling matches the terminal gauge requirements. Confirm that the jam nut installation method aligns with the panel thickness and mounting constraints of the target application before finalizing procurement.

Selection Notes

Select this component when a straight-mount receptacle with a bayonet lock is required for size 14 applications. The crimp termination option necessitates compatible wiring terminals. Evaluate the cadmium-plated aluminum housing against corrosion resistance requirements for the intended operational environment compared to alternative finishes.

Part Context

This part belongs to the PT08CP series within the broader MIL-DTL-26482 family of circular connectors. It serves as a standard interconnect solution for defense and aerospace sectors, bridging cable assemblies to panel-mounted equipment. The designation links directly to legacy Mil-Spec standards while maintaining modern manufacturing tolerances for interchangeability.

Replacement Considerations

Cross-reference with MS3474L14-12P or equivalent MIL-DTL-26482 Series I equivalents for direct mechanical and electrical substitution. Verify that mating interface dimensions and contact arrangements remain identical to prevent integration issues.
