Simrad RF45X Rugged Rudder Feedback Unit w/Tansmission Link, 2M Cable & Junction Box

Discover the Reliability of the Simrad RF45X Rudder Feedback Unit

Enhance your vessel's autopilot precision with the Simrad RF45X, a durable rudder feedback sensor designed for demanding marine environments. Unlike disposable alternatives, this unit stands out as a repairable solution, ensuring long-term dependability and cost savings for boat owners and professionals alike. Mounted directly near the rudder stock and linked mechanically via the included transmission arm, it delivers accurate angle data to your Simrad autopilot system, optimizing steering response and safety on the water.

Crafted for medium-duty applications, the RF45X thrives in harsh conditions, from rough seas to extended voyages. Its rugged construction minimizes downtime, while the bundled 2-meter cable and junction box simplify integration into your existing setup. Whether upgrading an older autopilot or outfitting a new build, this feedback unit provides the feedback loop your navigation electronics crave for smoother, more efficient operation.

Key Features That Set the RF45X Apart

• Robust IP56 Protection: Shields against water ingress, dust, and corrosion, making it ideal for exposed deck or engine room installations.
• Versatile Voltage Compatibility: Operates seamlessly on 12V or 24V systems, fitting a wide range of boats from small craft to larger yachts.
• Mechanical Transmission Link: Ensures precise, non-contact feedback without the wear associated with potentiometer-based sensors.
• Easy Installation Design: Comes pre-assembled with cable and junction box, reducing setup time and eliminating guesswork.
• Repairable Build: Modular components allow for field servicing, extending service life beyond typical "throwaway" sensors.

These attributes translate to superior performance: tighter autopilot tracking, reduced fuel consumption through efficient steering, and peace of mind knowing your system won't fail when you need it most.

How the Simrad RF45X Improves Your Autopilot Experience

Rudder feedback is the unsung hero of marine autopilots. Without it, your system lacks real-time insight into actual rudder position, leading to overcorrections, wandering courses, and increased helm wear. The RF45X changes that by providing continuous, high-resolution data—up to 3400 Hz compatibility in echo sounder integrations—enabling responsive adjustments that mimic an expert helmsman's touch.

Boat captains report noticeable gains in course stability, especially in choppy waters or during long passages. Pair it with Simrad NSS, NSO, or Precision-9 compass systems for a fully synchronized setup that handles everything from coastal cruising to offshore adventures.

Installation Tips for Optimal Performance

Position the RF45X as close as possible to the rudder stock for minimal linkage slop. Secure the transmission link to capture full rudder travel (typically 35-40 degrees port/starboard). Route the 2M cable away from high-vibration areas and electrical noise sources, using the junction box for clean terminations. Calibration is straightforward via your autopilot's menu—zero the sensor at amidships, then verify extremes. Regular checks on linkage tightness prevent drift over time, maintaining pinpoint accuracy.

Pro tip: In high-humidity installs, apply marine-grade sealant around mounting points to enhance longevity.

Maintenance and Longevity Advantages

What truly elevates the RF45X is its serviceable nature. Inspect the mechanical linkage annually for play or corrosion, and clean contacts in the junction box as needed. Should issues arise, disassemble for targeted repairs rather than full replacement—saving time and resources. This contrasts sharply with sealed units that demand complete swaps, often at premium costs.
