Product Overview

Hermetic D-Sub Connectors

Aptiv Interconnect's Hermetic D-Sub connectors are specialized D-shaped electrical connectors designed to provide a gas-tight or pressure-tight seal. They are essential for applications where sensitive electronics need isolation from external environmental factors like vacuum, high pressure, moisture, gases, and extreme temperatures. These connectors use glass-to-metal seals or ceramic/epoxy compounds for each contact, creating a reliable hermetic barrier. They are crucial in aerospace, defense, medical, industrial, and vacuum technology, ensuring stable signal, power, and data transmission across environmental barriers without compromising enclosure integrity.
