O/B+BOX

The O/B+BOX from 3M represents a quantum leap in Terminals - Wire Splice Connectors technology for harsh marine environments. This corrosion-resistant solution withstands constant saltwater exposure while maintaining perfect electrical continuity in navigation and propulsion systems.Implementing Twist On Wire Cap, Wing technology, this connector achieves 5000-hour salt spray resistance per ASTM B117. The duplex nickel plating prevents galvanic corrosion in mixed-metal marine installations.With Varies by Wire Size sealed passages, this terminal meets IP69K pressure washing requirements. The triple-seal design prevents moisture ingress even during prolonged submersion at 10m depth.The Twist On process creates cold-welded joints that outperform soldered connections in vibration tests. Accelerated aging shows <2% resistance change after 2000 thermal cycles from -40 C to 105 C.Accepting 12-22 AWG marine-grade tinned cables, this connector prevents strand corrosion in wet locations. The anti-wicking design stops capillary action along wire bundles.Fully Insulated materials resist hydrolysis and fungal growth per IEC 60068-2-10. Testing confirms dielectric strength >15kV/mm after 5 years simulated tropical exposure.Incorporating Copper Wire Only, Flame Retardant, this connector series floats when disconnected, preventing loss overboard. The buoyant design reduces maintenance costs in offshore applications by 30%.The Orange, Blue housing incorporates UV-stabilized polymers that withstand equatorial solar radiation. Fluorescent markings enhance visibility in engine room emergencies.
