Product Overview

The Cinch Dura-Con Hermetic Connectors offer a high-performance hermetic seal integrated into standard Dura-Con connectors. These connectors are available in both plug and socket configurations with 9, 15, 21, 25, 31, 37, and 51 positions. Featuring an aluminum shell for enhanced strength and EMI/RFI shielding, they are designed for harsh environments. Rugged twist-pin contacts provide resistance to shock and vibration. The hermetic seal is achieved using Cinch Hermetic compound and tested to Mil-DTL-83513 standards. Available in pigtail and solder cup variations, these connectors are ideal for demanding applications requiring robust sealing and reliable performance.
