Product Overview

The Cinch Dura-Con Hermetic Connectors offer a high-performance hermetic seal integrated into standard Dura-Con connector designs. Available in both plug and socket configurations with 9, 15, 21, 25, 31, 37, and 51 positions, these connectors feature an aluminum shell for enhanced strength and EMI/RFI shielding. Their rugged twist-pin contacts are resistant to shock and vibration, making the metal shell Dura-Con suitable for harsh environments. The hermetic seal is achieved using Cinch Hermetic compound and tested to Mil-DTL-83513 standards. Pigtail and Solder Cup variations are available.
