Raymarine SeaTalk^ng T-Piece Connector

The Raymarine SeaTalk ng T-Piece Connector is the essential junction component for modern marine navigation networks aboard fishing boats and cruisers. This compact connector bridges white SeaTalk ng spur cables to blue SeaTalk ng backbone cables, allowing you to expand your integrated marine electronics system without replacing existing wiring infrastructure. Whether you're upgrading a chart plotter, adding radar, or integrating new sounder transducers, this connector enables seamless data flow across your vessel's entire navigation ecosystem.

Built to Raymarine's marine-grade standards, the SeaTalk ng T-Piece Connector utilizes a proprietary connector design engineered for salt-water environments where corrosion and signal degradation threaten system reliability. The T-piece architecture allows you to connect multiple peripheral devices—networked sensors, autopilots, and digital switching modules—to a single backbone run without daisy-chaining or complex harness redesigns. Its minimal footprint (1 x 1 x 1 inch) and lightweight construction (0.05 lbs) make installation in tight helm spaces and behind bulkheads straightforward, reducing installation labor and minimizing cable clutter in an already space-constrained boat cabin.

Serious anglers and cruising boaters who have invested in Raymarine's SeaTalk ng ecosystem—including e-series displays, FLIR thermal cameras, and networked engine monitoring—will find this connector indispensable for system expansion. Installation is plug-and-play: simply disconnect your blue backbone cable at the desired node, insert the T-piece, and reconnect the backbone while adding your white spur cable to the perpendicular port. Compatibility is guaranteed across all current Raymarine networked devices using SeaTalk ng protocol, making this a future-proof addition to your vessel's electronics infrastructure.
