NMEA 2000 Connector System

Amphenol LTW NMEA 2000 Connector System is specifically designed to meet NMEA 2000 protocols and standards. This IP68-rated family of multi-port, standard, and metric circular connectors, sensors and actuator cables, and elbow joints. These products are ideal for connecting marine electronic equipment and display units within ships and boats. The NMEA 2000 lineup features high signal reliability, allowing multiple electronic devices to share data over one common channel. Starter kits are available in basic and professional packages to help build NMEA 2000 networks with varying levels of complexity. Amphenol LTW NMEA 2000 Connector System is suitable for a wide range of applications, such as fish finders, GPS receivers, autopilots, sonars, and audio systems.
