Overview

The Simrad 000-14377-001 is a 6 m (19.7 ft) NMEA 2000 Micro-C medium-duty network cable with male-to-female connectors and low-loss 18-gauge conductors.

Use it to extend a NMEA 2000 backbone between T-connectors, or to reach a device that sits farther from the nearest tee without resorting to splices. On boats where electronics are split between the helm, flybridge, engine space, and mast or transom sensors, the extra length helps keep the network layout clean and serviceable.

Because it uses the Micro-C connector style, it fits NMEA 2000 networks built with Micro-C tees, terminators, and power taps. If your boat uses a different connector family, plan on the correct adapter at the interface point.

Key features

• 6 m (19.7 ft) length for longer backbone sections or maximum-length runs where the layout requires it
• Micro-C male-to-female ends to link directly between tees, inline components, and backbone sections
• Medium-duty, low-loss 18-gauge conductors for runs where voltage drop becomes a concern as the network grows
• Standard NMEA 2000 Micro-C format used across many modern marine electronics networks

Compatibility and fit

This cable is for NMEA 2000 (Micro-C) networks. It is not an Ethernet cable and it does not replace NMEA 0183 wiring. If you are bridging between different connector styles such as SeaTalkNG or older SimNet layouts, use an adapter at the transition rather than forcing threads or pins to mate.

At 6 m, it also lines up with the common per-device drop-length limit used when planning NMEA 2000 layouts, which can matter when a display, engine gateway, or sensor has to be mounted a long way from the backbone.

Installation and routing

Route the cable where it will not be pinched by hatches, chafe on fiberglass edges, or rest against hot engine components. Support it along the run so the connectors are not carrying the cable's weight in rough water.

Micro-C connectors are meant to be hand-tightened. Keep junctions accessible for troubleshooting, and leave a small service loop so you can unplug devices without pulling on the backbone.

Who it suits

This is a practical pick for refits and new builds where the backbone needs to reach a second helm, an engine interface, or a sensor cluster without adding extra junctions. It also makes sense when you want a single continuous run between network tees rather than a chain of short extensions.
