Measuring 12 inches (approx. 305mm), this specialized adapter lead allows your smart shunt to broadcast vital battery telemetry directly to multi-function displays (MFDs), chartplotters, and central RV control panels via \u003cstrong\u003eNMEA 2000 (N2K)\u003c\/strong\u003e or \u003cstrong\u003eRV-C CANbus\u003c\/strong\u003e architectures.\u003c\/p\u003e\n\u003cp\u003eDesigned specifically for the \u003cstrong\u003eBalmar SG230, SG235, and SG240\u003c\/strong\u003e systems, this communications cable eliminates the need for complex field termination or delicate wire splicing. By utilising a factory-moulded harness, system integrators and DIY installers can achieve a reliable data link that maintains network integrity and ensures accurate, real-time visibility of state of charge (SoC), voltage, current draw, and battery health.\u003c\/p\u003e\n\u003ch3\u003eEngineered for Harsh Marine and Mobile Environments\u003c\/h3\u003e\n\u003cp\u003eData networks in boats, caravans, and motorhomes are routinely exposed to constant vibration, moisture, and temperature fluctuations. Standard data cables often suffer from signal drop-outs or corrosion at the terminal junctions. The Balmar SG2-0405 is built with industrial-grade interconnects to mitigate these risks and maintain continuous communication across your backbone.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandardised M12 DeviceNet Interface:\u003c\/strong\u003e Features a threaded 5-pin M12 circular male connector that locks securely into standard NMEA 2000 T-connectors and RV-C drop ports, preventing accidental disconnection in high-vibration environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeather-Sealed Rectangular Plug:\u003c\/strong\u003e Equipped with a multi-pin Deutsch-style female connector featuring an integrated orange weather seal, ensuring a moisture-resistant mate with the Balmar smart link architecture.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReinforced Junction Protection:\u003c\/strong\u003e Heavy-duty heat shrink tubing fortifies the transition zones between the flexible outer sheathing and the terminals, providing superior strain relief during tight routing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact 12-Inch (Approx. 305mm) Length:\u003c\/strong\u003e Minimises excess cable clutter behind dashboards, electrical cabinets, and battery bays while offering sufficient reach to connect to an adjacent network backbone drop.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClear Identification Sleeve:\u003c\/strong\u003e Includes a transparent protective heat shrink sleeve over the identification label, allowing technicians to easily verify part numbers and network routing during future system maintenance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhy Choose a Genuine Balmar Interconnect?\u003c\/h3\u003e\n\u003cp\u003eCANbus networks rely on precise impedance and shielding to prevent data packet loss and electromagnetic interference (EMI). Attempting to fabricate custom drop cables or using non-compliant adapters can introduce network faults that disrupt not only your battery monitor, but other critical devices sharing the NMEA 2000 or RV-C bus.
