Actisense: The NMEA Specialists in Marine Network Technology

Actisense was founded in 1996 when engineer and sailor Phil Whitehurst set out to make marine electronics simpler and smarter. Seeing too many devices fail in tough conditions, Phil built the brand around a commitment to reliable hardware, intelligent software, and industry-leading customer support. What started as a small operation on England's south coast has since grown into one of the most respected names in marine electronics worldwide.

A Global Leader in NMEA Technology

Actisense is a proud British manufacturer exporting to over 75 countries. Their award-winning brand has earned a reputation throughout the industry as "The NMEA Specialists," a title backed by genuine technical authority. Actisense's expertise has led them to become National Marine Electronics Association (NMEA) Committee members, helping to shape the industry standards of NMEA 0183, NMEA 2000, and the new NMEA OneNet®.

Actisense was named Manufacturer of the Year at the 2024 NMEA Conference and Expo, a recognition that reflects decades of engineering innovation and dedication to the marine community. The Actisense product portfolio includes data converters, buffers, multiplexers, network interfaces, and diagnostic tools that simplify and strengthen marine data systems.

What Actisense Makes

From NMEA 0183 and 2000 converters to diagnostic tools and smart interfaces, Actisense solutions make it easy to convert data, digitise signals, and share critical information reliably across marine systems. Whether you're outfitting a weekend sailboat or a commercial vessel, their products are engineered to perform in the harshest maritime conditions.

At the core of any Actisense-equipped boat is a robust NMEA 2000 interface cables and connectors network. These components form the backbone of onboard data communication, linking everything from chart plotters and depth sounders to autopilots and engine monitors. Actisense's expertise in this area is unmatched, and their connectors and cabling solutions are designed specifically to meet the demands of demanding marine environments.

Beyond connectivity hardware, Actisense offers a broad range of electronics parts and accessories that extend and enhance the capability of NMEA-based systems. From power management to signal distribution, these accessories help mariners build cleaner, more capable onboard networks. For those focused on situational awareness and voyage planning, the brand's navigation parts and accessories tie seamlessly into the wider NMEA ecosystem, enabling reliable data flow to the instruments that matter most.
