Dura-Con Hermetic Connectors
Product Overview
Cinch Dura-Con Hermetic Connectors offer a high-performance hermetic seal integrated into standard Dura-Con connectors. 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 an excellent choice 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.
