Baro posūkio jutiklis RF25N - NMEA 2000 - 5,5 m kabelis

The RF25N rudder angle sensor provides the autopilot computer with the exact rudder position, enabling smoother, more responsive, and precise course-keeping.

Designed by Navico, it is ideally compatible with autopilots from Simrad and B&G operating on an NMEA 2000 network.

It connects very simply, directly to your NMEA 2000 network (standard Micro-C connector) via its integrated cable. No intermediate conversion box is required.

The sensor comes with a 5.5-metre (18-foot) NMEA 2000 cable, providing ample length for routing from the bilge up to the backbone of the network.

Yes, it meets IP56 waterproofing standards, making it fully suitable for humid environments and typical water splashes in boat bilges.

It delivers a formidable accuracy of ±0.25° (within a ±5° range) and exceptional repeatability of ±0.1°.

The RF25N can measure a rudder angle of up to ±120 degrees, covering the travel range of the vast majority of steering systems.

No, no external power supply is required. The sensor is directly powered by the NMEA 2000 network (operating voltage between 8 and 16V DC).

Its power consumption is extremely low, measured at just 0.4W. This corresponds to a NMEA 2000 load index (LEN) of 1.

Yes, its versatile mechanical design allows installation either horizontally or vertically, easily adapting to the specific configuration of your rudderstock.

To avoid any magnetic interference, it is recommended to maintain a minimum safety distance of 1 metre (3.1 feet) from any steering compass.

The housing is made of robust Arnite T06 200 PBT thermoplastic, a material specifically selected to withstand mechanical stress and harsh marine conditions.

The sensor is designed to operate optimally within extreme temperatures ranging from -25°C to +55°C (-13 to +131 °F).

It transmits rudder position and angle data via the standard NMEA 2000 PGN 127245 signal.

The sensor weighs approximately 0.5 kg (1.1 lbs), making it a lightweight unit that does not add significant weight to your autopilot system.

The sensor itself is designed for a voltage of 8 to 16V. It must be connected to a standard NMEA 2000 backbone, which is by definition always powered at 12V, even if the rest of the boat is 24V.

Although it uses the NMEA 2000 standard, the RF25N is specifically optimized to natively integrate without latency into the Navico ecosystem (Simrad, B&G). It is the ideal solution for replacing a faulty sensor on these systems.

Yes, once mechanically installed and connected to the NMEA 2000 network, it is mandatory to perform a calibration via your autopilot’s control screen to set the zero point (rudder amidships) and maximum limits.

Yes, the cable terminates in a standard Micro-C connector, ready to be screwed directly onto a T-connector on your NMEA 2000 backbone.

A physical sensor like the RF25N provides real-time and instantaneous position data to the computer. This reduces unnecessary actuator movements, lowers overall power consumption, and delivers a much smoother trajectory than a virtual rudder feedback (VRF) calculation.
