Belfuse Cinch DMS-TP Dry-mated Sealed Connectors
Product Overview
The Cinch DMS-TP Dry-mated Sealed Connectors are designed to meet the highest safety standards for harsh environment applications. Developed as a solution for challenges in the Oil and Gas industry, these connectors have demonstrated effectiveness in demanding conditions involving prolonged exposure to oil, gas, sand, mud, hydrocarbons, and salt. They are ideal for environments with extreme temperature fluctuations, pressure variations, high humidity, and intense vibration. These dry-mated connectors offer high performance and cost efficiency, featuring nickel-plated brass shells for excellent corrosion resistance, high electrical conductivity, and resistance to biological fouling. Reliable water tightness is ensured by two O-rings in the coupling interface. The scoop-proof design facilitates blind mating and enhances pin integrity, making them suitable for high contact density layouts. Cinch Connectivity Solutions Mil/Aero Circular connectors provide a robust solution for harsh or demanding environments against physical and environmental conditions.
