Em-Trak 431-0001 B924 Class B AIS Transponder

The Em-Trak 431-0001 is a Class B AIS Transponder designed for recreational and commercial marine vessels. Automatic Identification System (AIS) technology allows your vessel to broadcast its position, speed, course, and identity to nearby ships and shore stations, while simultaneously receiving the same data from other AIS-equipped vessels — significantly improving situational awareness and collision avoidance at sea.

Key Features:

• Class B SOTDMA AIS transponder for reliable, continuous position broadcasting
• Dual-channel simultaneous receive on AIS channels 87 and 88
• Compact, low-profile design suitable for a wide range of vessel installations
• NMEA 0183 and NMEA 2000 connectivity for integration with chartplotters and MFDs
• Built-in GPS receiver for standalone operation
• Low power consumption for extended underway use
• Complies with ITU-R M.1371, IEC 62287, and applicable FCC/Industry Canada regulations

The Em-Trak 431-0001 integrates seamlessly with major marine navigation systems and is suitable for sailboats, powerboats, and other recreational vessels requiring dependable AIS performance. Its compact footprint and straightforward NMEA connectivity make installation straightforward for both new builds and retrofit applications.
