Furuno 000-010-913 Single JB N NMEA2000 FI50

The Furuno 000-010-913 Single JB N NMEA2000 FI50 is a precision mast-step junction box designed for marine electronics integration on small to mid-sized vessels. This component serves as a critical connection point in NMEA 2000 network installations, enabling reliable communication between wind instruments, navigation systems, and other networked marine sensors. Whether you're upgrading your existing marine electronics suite or building a new integrated system, this junction box provides the foundation for seamless data flow across your vessel's navigation network.

Built to Furuno's exacting marine standards, the FI50 junction box features NMEA 2000 protocol compatibility, ensuring plug-and-play integration with certified marine electronics. The mast-step design allows for optimal placement near your wind instrument sensor, minimizing cable runs and signal degradation in high-noise marine environments. At just 0.05 lbs, this compact unit is engineered for minimal weight penalty while delivering robust electrical isolation and noise filtering. The device is sealed against salt spray and moisture intrusion—critical for above-deck or mast-mounted installations where corrosion and environmental stress are constant concerns.

Marine installers and system integrators rely on this junction box to simplify NMEA 2000 backbone deployments, particularly in wind data applications requiring dedicated signal conditioning. It is ideal for retrofit installations where existing mast cabling and sensor locations need to be preserved. Compatibility with Furuno FI5001 wind instruments and other NMEA 2000–certified devices makes this a trusted choice for cruisers, fishing vessels, and professional maritime operators seeking reliable, future-proof marine electronics architecture.
