Enhance your vessel's autopilot performance with the Simrad RF25N rudder feedback unit, a reliable medium-duty sensor designed for marine environments. This unit delivers precise rudder angle data straight to your NMEA 2000 network via its Micro-C connection, ensuring smooth and responsive steering even in demanding conditions. Whether you're navigating coastal waters or tackling offshore passages, the RF25N helps maintain course accuracy by feeding real-time feedback to your Simrad autopilot system.

Built to withstand the rigors of boating, it features robust construction with IPX6 water resistance, making it ideal for spray, rain, or unexpected splashes. The included 5-meter Micro-C cable and linkage kit simplify setup, allowing you to connect directly without extra adapters. Mariners appreciate its straightforward integration, which minimizes wiring hassles and gets you back on the water faster.

Key Features That Set the RF25N Apart

• Wide Measurement Range: Captures rudder positions from -120° to +120°, covering full travel for most setups.
• Exceptional Precision: Accuracy within ±0.5°, providing the fine-tuned data autopilots need for stable tracking.
• Plug-and-Play Connectivity: Micro-C interface mates seamlessly with NMEA 2000 backbones used in Simrad NSS, NSO, and NSX multifunction displays.
• Durable Design: Operates reliably on 12-16V systems, proven in harsh saltwater exposures.
• Complete Kit: Comes with a 5m cable and mounting linkage for immediate installation.

Unlike basic feedback sensors, the RF25N stands out for its rotary design that tracks movement without slippage, reducing wear and maintaining calibration over seasons of use.

How the RF25N Boosts Your On-Water Experience

Imagine setting your autopilot for a long troll or crossing and trusting it to hold course without constant adjustments. The RF25N makes this possible by relaying exact rudder position to your chartplotter or autopilot brain. This leads to less fuel consumption from overcorrections, fewer helm interventions during night watches, and safer handling in rough seas where manual steering fatigues quickly.

For fishing boats, it shines during drifts or fights with big game, keeping the bow into wind without drifting off. Sailors benefit from tighter tacking angles and wind-holding in gusts. Even recreational cruisers notice the difference in relaxed passages, freeing crew to enjoy the journey.

Installation Insights for Smooth Setup

Mount the sensor near the rudder stock using the supplied linkage—aim for a position shielded from direct propeller thrust. Calibrate via your Simrad display's autopilot menu, and you'll see immediate improvements in response time. It's compatible with popular setups like the NAC-2 or NAC-3 pilots, extending to B&G and Lowrance systems sharing NMEA 2000.

Pro tip: Regularly inspect the linkage for play and rinse with freshwater after saltwater exposure to extend its lifespan.

Why Boaters Trust Simrad Rudder Feedback

Simrad's engineering focuses on real-world reliability, drawing from decades of feedback from commercial and recreational users. The RF25N isn't just a sensor; it's a component that ties your navigation suite together, supporting features like arrival circles, man-overboard tracking, and dynamic headings. Its medium-duty rating handles typical recreational loads up to larger sportfishers, striking a balance between cost and capability.
