• Marine navigation and communication equipment housings

Procurement Notes

Verify the exact shell size, insert arrangement, and plating specification against the original equipment manufacturer (OEM) bill of materials. Ensure compatibility with the intended cable diameter and strain relief requirements. Confirm that the housing material and finish meet the specific environmental standards required for the target installation site.

Selection Notes

Select this housing based on the required mating interface and environmental protection level. Consider the operating temperature range and chemical exposure risks when validating material suitability. Ensure the chosen configuration aligns with existing panel cutout dimensions and mounting hardware constraints to maintain system integration integrity.

Part Context

This component belongs to the MIL-DTL-38999 family of circular connectors, widely utilized in critical military and aerospace platforms. The Series III designation indicates a lightweight, high-density variant compared to earlier generations.
