Raymarine Wireless Mast Rotation Transmitter

Description

The Raymarine T120 is a wireless mast rotation transmitter for Micronet sailing systems. It does not display wind, heading, or charts; its job is to measure mast rotation and send that information wirelessly to compatible Micronet displays. This makes it useful on boats with rotating masts or installations where mast movement needs to be accounted for in the sailing data.

The solar-powered, self-contained unit avoids a separate power cable at the mast position, while the IPX6/IPX7 protection suits exposed mounting. A Micronet wireless encoder measures the rotation angle and passes it to the compatible display network. There are no wired networking ports, and the supplied information does not identify direct NMEA 2000 or NMEA 0183 operation. It is a system accessory, not a standalone sensor display.

Key Features

• High-precision mast rotation sensing – Provides rotation-angle data for compatible sailing instruments.
• Micronet wireless output – Sends the sensor data without a wired network connection.
• Solar powered and self-powered – Avoids a separate supply cable at the mast location.
• IPX6 and IPX7 protection – Suits exposed masthead and marine mounting conditions.
• Compact masthead mounting – Fits the listed sensor installation position.

Who Is This For?

This wireless mast sensor suits sailing boats with a Raymarine Micronet system that needs mast rotation data. It is not ideal as a general wind sensor or standalone instrument, because it provides no display and depends on compatible Micronet equipment to use its output.

Compatibility

Confirmed compatibility includes Micronet wireless displays and compatible Raymarine sailing instruments. The supplied information does not identify direct NMEA 2000, NMEA 0183, Garmin, B&G, Simrad, radar, sonar, or autopilot compatibility. No named incompatible system was provided; verify the Micronet display and transmitter requirements before installation.

The T120 is a small but important accessory when a Micronet sailing system needs accurate mast rotation information. Its advantage is simple installation without a dedicated power or data cable at the mast. The trade-off is compatibility: it only makes sense as part of the appropriate Raymarine Micronet setup, not as a standalone wind or navigation sensor.
