Simrad NMEA 2000 Micro-C Medium Duty Cable, 6 m, 18 Gauge

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.

Shipping
We ship worldwide from the United States. Rates are calculated at checkout based on destination and package weight. Some items include free shipping, which will show automatically. Not every product is eligible for international shipping; checkout will confirm eligibility. We do not ship to PO Boxes except through USPS, and not all packages qualify.

Processing and dispatch
Most orders are verified, packed, and handed to the carrier within 1 to 2 business days. Some products may need extra handling time or ship directly from the manufacturer. For certain international orders, inventory transfers between warehouses may add time. If any delay is expected, we will let you know the dispatch date.

Delivery and tracking
Deliveries are handled by trusted carriers such as USPS, UPS, FedEx, and DHL. Estimated arrival times appear at checkout and depend on your location and the service you choose. These are estimates and can be affected by customs or carrier disruptions. A shipping confirmation with a tracking link is emailed when your order ships, and tracking may take up to 24 hours to update. You can also view tracking in your account.

Duties, taxes, and support
International customers are responsible for any customs duties, taxes, and fees charged by the destination country. If these charges are refused and a shipment returns to us, the carrier’s return cost and any re-entry customs fees will be deducted from the refund. If your order is late or you need help, contact cs@qualityboatparts.com and we will assist you.

Quality Boat Parts is a reseller. Many items include a manufacturer’s warranty, and all warranty service is handled directly by the manufacturer. We do not manage or administer warranty claims on behalf of customers.

Warranty terms, coverage, and duration are set by each manufacturer. Issues involving defects, repairs, or replacements must be addressed with the manufacturer’s support team. When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.

We are happy to help you find the right contact or documentation, but we cannot decide outcomes or intervene in claim resolutions. For guidance, email cs@qualityboatparts.com.
