Simrad 22011415 RF45X Rudder Feedback Unit

Simrad RF45X Heavy-Duty Rudder Feedback Unit

The Simrad 22011415 (Model: RF45X) is a commercial-grade, highly precise rudder feedback unit (RFU) designed for autopilot systems on commercial vessels, superyachts, workboats, and heavy displacement craft. It converts mechanical rudder stock rotation into dual proportional electrical feedback signals—frequency (3400 to 4000 Hz) and 4 to 20 mA current loop—allowing direct integration with Simrad commercial autopilot computers (such as AP70 Mk2, AP80, AC70) as well as third-party steering gear controllers and marine computer interfaces.

Housed in a rugged, marine-grade cast aluminum casing with a stainless steel transmission shaft and linkage rod, the RF45X is built to withstand high vibration, shock, and continuous exposure in steering compartments. It features an integrated transmission link with adjustable length and self-aligning ball joints for alignment with the rudder tiller arm.

Key Features

• Dual Output Signals: Generates both frequency-modulated digital output and an analog 4-20 mA current loop signal for maximum compatibility with commercial steering systems.

• Heavy-Duty Construction: Rugged, sealed cast aluminum housing with stainless steel hardware designed for demanding commercial marine environments.

• Precise Linear Measurement: Delivers continuous, high-resolution angular position tracking (±45° standard rudder angle movement).

• Includes Linkage Hardware: Supplied complete with transmission lever arm, ball joints, and adjustable transmission rod for direct attachment to the rudder stock tiller.
