High density interconnect Amphenol D3899933W25R connector suitable for aerospace and military systems

High Density Interconnects HD38999 Series Connectors

Product Overview

The Amphenol HD38999 series connectors offer significantly increased contact density, providing up to 30% more contacts than standard MIL-SPEC 38999 connectors of the same size. Designed to utilize mil-specified 38999 components, including size 23 contacts and insert materials, these connectors serve as a direct replacement for standard 38999 connectors. This series is ideal for applications requiring higher contact counts without increasing connector size, or for system size reduction by using smaller shell sizes while maintaining contact count. The HD38999 series has been qualified to MIL-DTL-38999 requirements and is available in Filter, Hermetic, and customized versions.
