Product details
Developed by Keystone Electronics, the 981TR 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 Jack design incorporates pressure-balanced oil-filled (PBOF) technology. Unlike standard connectors, its compensated design prevents water ingress at 3000m depths.Female variants feature titanium housings for submerged applications. The cathodic protection prevents galvanic corrosion in seawater environments.Capable of Stereo (3 Conductor, TRS) 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 0.142" (3.60mm) precision, the connector withstands 20,000psi hydrostatic pressure. The forged brass construction resists deep-sea crushing forces.With 3 Conductors, 5 Contacts, the interface supports power-over-fiber applications. The hybrid design combines optical and electrical contacts in single housing.The Two Switches implementation includes seawater detection. The sacrificial anode protects contacts during accidental immersion.The Surface Mount, Right Angle 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 Board Guide include ROV-operable coupling mechanism. The torque-balanced design enables remote subsea connection.
