Sierra PC51000 NMEA 2000 Micro-C Extension Cable — 2 ft
The Sierra PC51000 is a 2 ft Micro-C extension cable designed to extend or connect devices on an NMEA 2000 network backbone. NMEA 2000 is the marine industry standard data network that allows compatible electronics — chartplotters, GPS sensors, depth sounders, engine monitors, VHF radios, and more — to share data over a single cable network. This extension cable uses the standard Micro-C connector format and is fully interchangeable with other NMEA 2000 certified products. Gold-plated copper alloy terminals, 18AWG conductors, and an IPX7-rated waterproof connection ensure reliable, low-loss signal transmission in demanding marine environments.
Key Features
- 2 ft Micro-C extension cable for NMEA 2000 network backbone connections
- Fully interchangeable with other NMEA 2000 certified products
- Gold-plated copper alloy terminals for superior conductivity and corrosion resistance
- 18AWG conductors — minimizes voltage drop between connections
- IPX7-rated waterproof connections — reliable in wet and spray environments
- Premium metal connection collars for a tight, secure fit
- Compliant with NMEA 2000 serial data communication network standards
Compatible Applications
- Extending NMEA 2000 backbone runs on powerboats and sailboats
- Connecting chartplotters, GPS sensors, depth sounders, and engine monitors to an NMEA 2000 network
- Short backbone extensions where a 2 ft cable suits the gap between devices or T-connectors
- Any NMEA 2000 Micro-C network installation requiring a certified extension cable
Parts Desk Insights
The PC51000 is the shortest extension in the Sierra NMEA 2000 range — the right pick when a customer needs to bridge a small gap on the backbone or reach a device that’s just out of range of the existing run. If 2 ft isn’t enough, the Sierra PC51010 (3 ft), Sierra PC51020 (6 ft), and Sierra PC51030 (12 ft) cover longer backbone runs. For connecting individual devices off the backbone rather than extending it, the drop cables — Sierra PC51140 (2 ft Drop), Sierra PC51160 (6 ft Drop), and Sierra PC51170 (16 ft Drop) — are the correct cable type. To power the network, the Sierra PC51070 Power T Cable is also available. Browse our full NMEA 2000 range in the Switches & Circuit Protection collection.
