Maretron NMEA 2000 Sensors & Cables

Maretron builds the sensors, monitors, and cables that turn an NMEA 2000 network into a complete vessel monitoring system. Instead of guessing, you can watch tank levels, temperatures, battery and AC status, bilge water, and gas detection from a single display. This collection covers Maretron sensors, monitoring modules, network cables, and connectors. Building it right comes down to choosing the sensors you need and wiring a solid network.

Pick the sensors that matter

Maretron offers a wide sensor range: tank level monitors for fuel, water, and waste, temperature and pressure probes, AC and DC monitors that track voltage, current, and battery state, bilge and high-water detectors, and carbon monoxide and smoke detection. Start with what you most want to know, often fuel and water levels, battery health, and bilge status, then expand the system over time.

Everything rides the NMEA 2000 backbone

Maretron sensors report over NMEA 2000, so they share data with your chartplotter and any compatible display. Build the network with a proper backbone, drop cables to each device, terminators at both ends, and a power tap sized for the load. A clean, correctly terminated backbone is the difference between reliable data and a network that drops out.

Match cables and connectors

Maretron uses field-attachable and molded NMEA 2000 cables and connectors in mid and micro sizes. Measure your runs, use the right cable length and gender, and add tees where devices branch off. Quality cabling keeps the network solid in a wet, vibrating environment.

Displays and alarms

A Maretron display like the DSM series, or any compatible NMEA 2000 screen, shows the data and can alarm on conditions you set, like high bilge water or low voltage. Alarms are the real payoff, because catching a problem early at the dock beats discovering it underway.

Plan for expansion

One advantage of a networked system is that you can add sensors as needs grow. Leave room on the backbone and a few spare drops so the next sensor is a plug-in, not a rewire.
