Product details
3M's BS-31-4S sets new benchmarks in Terminals - Spade Connectors technology for marine electronics. This corrosion-resistant connector meets DNV-GL standards while providing reliable performance in saltwater environments. Its innovative design addresses the unique challenges of offshore and deep-sea applications.The Standard configuration provides IP69K protection against high-pressure seawater ingress. Unlike standard marine connectors, this design maintains performance at 500m depth.Engineered with 4 Stud compatibility, this terminal prevents galvanic corrosion in mixed-metal boat systems. The titanium construction resists pitting in saltwater.Precisely manufactured to 0.250" (6.35mm) specifications, this connector prevents barnacle accumulation. The hydrodynamic profile reduces drag on underwater sensors.The 0.650" (16.50mm) design incorporates positive buoyancy features for surface recovery. This safety characteristic is critical for sonar buoy applications.Optimized for Free Hanging (In-Line) installations, this connector enables one-handed operation in rough seas. The magnetic alignment assists docking in low-visibility conditions.Utilizing Crimp technology, this connector achieves gas-tight joints that prevent electrolysis. The process is validated for permanent underwater installations.Designed for 18-22 AWG marine cabling, this terminal maintains signal integrity in lightning-prone areas. The spark-gap design protects sensitive oceanographic instruments.The Non-Insulated material exceeds ASTM B117 salt spray requirements for 5000+ hours. Special hydrophobic coatings prevent water tracking along conductors.Incorporating Butted Seam, this connector provides cathodic protection monitoring. The integrated reference electrode detects coating damage before corrosion begins.Tin plating provides <2m resistance after 10 years seawater immersion. The nano-crystalline structure prevents chloride penetration.The Copper, ETP formulation offers perfect balance between conductivity and corrosion resistance. Advanced nickel-copper alloys outperform traditional marine bronzes.
