Product details
Curtis Industries's 431405-21-0 redefines Terminal Blocks - Barrier Blocks standards for underwater robotics and subsea instrumentation. This pressure-compensated terminal block maintains perfect sealing at 6000m depths while resisting saltwater corrosion. Its oil-filled design and advanced polymer chemistry enable decades of reliable operation in ROV and AUV applications.The Barrier Block configuration provides hydrostatic pressure compensation without moving parts.With 21 pressure-balanced circuits, it supports complex sensor arrays on oceanographic equipment.The 21 penetrator design maintains IP68 rating at full ocean depth pressures.0.438" (11.12mm) marine-grade spacing prevents dendritic growth in long-term submerged applications.The 1 row layout optimizes pressure distribution across the housing.Rated for 20A in conductive seawater environments, it exceeds ABS underwater equipment standards.600V isolation prevents electrolysis in seawater power distribution systems.Compatible with 12-22 AWG marine cables, including oil-filled and gel-insulated types.The Screws (Not Included) system maintains gas-tight seals throughout thermal cycling.Quick Connect (0.187") interface provides strain relief for dynamic cable applications.2 Wall (Dual) barriers prevent cathodic disbondment in submerged metal structures.
