{"product_id":"qbp713490","title":"Simrad RF45X Rudder Feedback Unit, 12-24VDC, Transmission Link, 2m Cable","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe Simrad 22011415 is a rugged rudder feedback unit that sends rudder position information to a compatible Simrad autopilot system, or to a standalone rudder angle indicator setup. It mounts close to the rudder stock and connects mechanically to the rudder via the included transmission link in a 1:1 ratio, so the sensor shaft tracks rudder movement directly.\u003c\/p\u003e\u003cp\u003eIt runs from a 12 to 24 VDC supply and comes with a 2 m screened cable and a junction box for splicing and tidy wiring in the steering compartment. For autopilot use it outputs a variable frequency signal centered at 3400 Hz, varying at about 20 Hz per degree, and it also supports a variable current output of 0.1 to 1.1 mA for indicator systems.\u003c\/p\u003e\u003cp\u003eThis is a good fit for boats where the autopilot needs true rudder angle feedback for steering accuracy and alarms, especially on vessels with a traditional rudder stock and linkage access near the quadrant or tiller arm.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003e12 to 24 VDC supply support for common onboard electrical systems\u003c\/li\u003e\n\u003cli\u003eVariable frequency output for autopilot feedback, centered at 3400 Hz (about 20 Hz per degree)\u003c\/li\u003e\n\u003cli\u003eVariable current output (0.1 to 1.1 mA) for use with compatible rudder angle indicators\u003c\/li\u003e\n\u003cli\u003eMechanical connection via transmission link in a 1:1 ratio, mounted close to the rudder stock\u003c\/li\u003e\n\u003cli\u003eSupplied with a 2 m screened lead and a junction box for splicing and protected connections\u003c\/li\u003e\n\u003cli\u003eCan be mounted with the shaft pointing up or down, with deflection inversion available for upside-down installs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and setup\u003c\/h6\u003e\u003cp\u003eMount the unit on a rigid surface near the rudder stock where the transmission link can move freely through the full steering travel without binding. The linkage is typically arranged in a parallelogram so the sensor shaft rotates smoothly as the rudder moves. If needed, the transmission rod can be shortened to suit your geometry, as long as the linkage remains straight and free through hard-over to hard-over movement.\u003c\/p\u003e\u003cp\u003eAfter the mechanical linkage is set with the rudder centered, complete the rudder zero and calibration steps in your autopilot or indicator setup so the displayed angle matches the actual rudder position. If you install the sensor with the shaft pointing down, use the available inversion method so port and starboard deflection reads correctly.\u003c\/p\u003e\u003ch6\u003eCompatibility and system integration\u003c\/h6\u003e\u003cp\u003eThis unit is used with Simrad autopilot systems that accept an RF45X-type rudder feedback input and can also be wired into a standalone rudder angle indicator system using the current output. Output selection is configurable, so confirm which input type your control unit or indicator expects before final wiring.\u003c\/p\u003e\u003cp\u003eThe supplied 2 m lead is intended to be spliced in the junction box. When extending wiring, keep runs as short as practical and use screened, twisted-pair cabling to reduce noise in a steering compartment that often shares space with pumps, solenoids, and high-current wiring.\u003c\/p\u003e\u003ch6\u003eMaintenance and care\u003c\/h6\u003e\u003cp\u003ePeriodically check the transmission link, fasteners, and any ball joints for play, corrosion, or misalignment, and confirm the linkage still moves smoothly through the full rudder travel. Keep the junction box closed and dry, and re-check rudder zero if any steering components are serviced or adjusted.\u003c\/p\u003e\u003ch6\u003eWhat’s included\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eRF45X rugged rudder feedback unit\u003c\/li\u003e\n\u003cli\u003eTransmission link\u003c\/li\u003e\n\u003cli\u003e2 m cable\u003c\/li\u003e\n\u003cli\u003eJunction box\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Simrad","offers":[{"title":"Default Title","offer_id":52269088571573,"sku":"QBP713490","price":769.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1298551_qbp713490.jpg?v=1771541802","url":"https:\/\/www.qualityboatparts.com\/products\/qbp713490","provider":"Quality Boat Parts","version":"1.0","type":"link"}
