Collection: NMEA Cables & Sensors

Building or expanding a marine electronics network requires matching every component to the right protocol. This category covers NMEA 2000 backbone hardware from Ancor, including starter kits, terminators, blanking caps, field serviceable connectors and through bulkhead adaptors, alongside sensors and converters from Raymarine, Garmin, Maretron and Digital Yacht. NMEA 2000 runs as a shared powered bus where devices connect via drop cables, while NMEA 0183 such as the Garmin GPS 19x HVS requires a point-to-point wire run to each receiving instrument.

Before buying, confirm which protocol your chartplotter and instruments support. Raymarine SeaTalk users will need a converter before integrating newer SeaTalkng components. Thru-hull sensors such as the Raymarine DST820 multisensor require checking hull thickness and material compatibility before ordering. The Maretron BHW100 bilge high water detector adds network monitoring without a dedicated display. To share one antenna between a VHF radio and AIS receiver, a powered splitter such as the Digital Yacht SPL2000 handles that. For NMEA 2000 builds, check connector gender on existing hardware and confirm backbone termination is in place before adding drop cables.
