Product details
Developed by CUI Devices, the SP-3540 Barrel - Audio Connectors sets new standards for marine electronics connectivity. This DNV-GL certified solution delivers corrosion-resistant performance in sonar systems, navigation equipment, and offshore communication networks while resisting saltwater immersion.The Phone Plug design incorporates pressure-balanced oil-filled (PBOF) technology. Unlike standard connectors, its compensated design prevents water ingress at 3000m depths.Male variants feature titanium housings for submerged applications. The cathodic protection prevents galvanic corrosion in seawater environments.Capable of Stereo (4 Conductor, TRRS) operation, the connector handles underwater acoustic signals. The matched-impedance design minimizes signal reflection in long cable runs.The 3.50mm (0.141", 1/8", Mini Plug) - Headphone complies with IEC 60529 IP68 standards. The double-seal mechanism guarantees leak-proof performance after 5000 mating cycles.Engineered to 0.126" (3.20mm) precision, the connector withstands 20,000psi hydrostatic pressure. The forged brass construction resists deep-sea crushing forces.With 4 Conductors, 4 Contacts, the interface supports power-over-fiber applications. The hybrid design combines optical and electrical contacts in single housing.The Does Not Contain Switch implementation includes seawater detection. The sacrificial anode protects contacts during accidental immersion.The Free Hanging (In-Line) format enables hull penetration installations. The anti-fouling coating prevents marine growth accumulation.Solder method utilizes hydrostatic pressure crimping. The process creates gas-tight seals without thermal damage to insulation.Featuring Unshielded effectiveness, the connector reduces underwater electromagnetic interference. The coaxial design maintains <1dB signal loss per 100m in seawater.The Cover, Strain Relief include ROV-operable coupling mechanism. The torque-balanced design enables remote subsea connection.Black options meet maritime visibility requirements. The photoluminescent markings glow for 8+ hours after light exposure.Rated for -25°C ~ 70°C, the connector maintains performance in Arctic drilling operations. The material selection prevents brittleness at -50 C.
