Product details
Littelfuse Inc.'s 4721-P4 redefines Terminal Strips and Turret Boards technology for marine and offshore electronics. This corrosion-resistant terminal strip is engineered to withstand salt fog, humidity, and mechanical shock in harsh maritime environments. The 4721-P4 delivers reliable performance for navigation systems, sonar equipment, and offshore energy platforms with IP68-rated protection.The marine-grade Terminal Strip configuration features gold-over-nickel plating with additional palladium barrier layers for saltwater corrosion resistance.Threaded Stud contacts employ gas-tight crimp technology that maintains <5m resistance after 500 hours salt spray testing.With 4 positions, the design supports redundant power distribution networks required by SOLAS regulations.The 1 row architecture allows separation of essential and non-essential circuits as per IMO safety standards.The 3.870" L x 0.625" W x 0.844" H (98.30mm x 15.90mm x 21.40mm) form factor fits standard marine equipment racks with vibration-damping mounting provisions.Constructed from Phenolic laminate, the substrate resists fungal growth and hydrolytic degradation.Marine-specific Flange include sacrificial zinc anodes for cathodic protection and anti-fretting contact designs.
