Product Overview

Hermetic Sub-C Connectors

Aptiv Interconnect Hermetic Sub-C connectors are compact, circular electrical connectors designed for robust, gas-tight, or pressure-tight seals through panels. They isolate sensitive electronics from harsh environments like vacuum, high pressure, moisture, and extreme temperatures. "Sub-C" refers to a compact circular form factor, smaller than standard MIL-SPEC but larger than microminiature connectors. These connectors feature durable metal shells and advanced hermetic sealing (glass-to-metal or ceramic/epoxy) for long-term environmental integrity. They are vital in aerospace, defense, medical, industrial, and oil & gas applications requiring reliable sealed interfaces for power, signal, or data transmission.
