Product details
TE Connectivity AMP Connectors's 3-1546159-7 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 20 pressure-balanced circuits, it supports complex sensor arrays on oceanographic equipment.The 20 penetrator design maintains IP68 rating at full ocean depth pressures.0.375" (9.53mm) marine-grade spacing prevents dendritic growth in long-term submerged applications.The 1 row layout optimizes pressure distribution across the housing.Rated for 25A in conductive seawater environments, it exceeds ABS underwater equipment standards.300V isolation prevents electrolysis in seawater power distribution systems.Compatible with 12-22 AWG marine cables, including oil-filled and gel-insulated types.The Screws with Captive Plate system maintains gas-tight seals throughout thermal cycling.Wire Wrap interface provides strain relief for dynamic cable applications.3 Wall (Tri) barriers prevent cathodic disbondment in submerged metal structures.The Positions Stamped implementation addresses unique challenges in deep-sea electrical systems.The Black housing incorporates biofouling-resistant additives for long-term deployment.
