KONGSBERG RUDDER FEEDBACK UNIT (RFU) 309564

Product Overview

The KONGSBERG Rudder Feedback Unit (RFU) 309564 is a marine rudder angle position sensor engineered for Kongsberg marine autopilot and steering gear control systems, designed in compliance with DNV marine certification and IEC 60945 marine EMC standards. Built for rudder angle position detection, mechanical rotation conversion & analog position signal transmission, this rugged marine sensor withstands steering compartment salt mist, mechanical vibration and wide temperature fluctuation, delivers stable continuous operation, and provides accurate rudder position feedback for merchant vessels, offshore supply ships and dynamic positioning vessels fitted with Kongsberg marine steering and autopilot systems.

Featuring high precision rotary potentiometer sensing element, sealed corrosion resistant housing & shielded signal output interface. Both rudder stock bulkhead mounting and steering gear local installation are supported, adapting to limited installation space inside vessel steering compartments and aft machinery rooms. The modular assembly allows separate replacement of the sensing core without full vessel steering control system shutdown, greatly reducing equipment downtime for service. Equipped with mechanical limit stop protection, IP66 environmental sealing & vibration resistant internal structure, mature hardware structure prevents signal drift and guarantees reliable rudder angle feedback during continuous duty.

For dependable rudder angle position detection, mechanical rotation conversion & analog position signal transmission, this Kongsberg RFU 309564 mechanically couples with rudder stock, converts physical rudder deflection into proportional electrical signals and sends real-time rudder angle data to autopilot and steering gear controllers. Reliable rudder angle position detection, mechanical rotation conversion & analog position signal transmission, premium marine-grade sensing components provide excellent humidity and salt corrosion resistance, extending service life in harsh marine steering compartment working environments. Practical mechanical limit stop protection, IP66 environmental sealing & vibration resistant internal structure, precise angle conversion lowers position deviation during long-hour operation, ensuring accurate steering control under variable sea conditions.

During continuous rudder angle position detection, mechanical rotation conversion & analog position signal transmission, this rudder feedback sensor is fully compatible with Kongsberg marine autopilot and steering gear automation platforms. Stable rudder angle position detection, mechanical rotation conversion & analog position signal transmission, mature Kongsberg maritime sensing technology with easy spare parts replacement and convenient after-sales maintenance. Robust mechanical limit stop protection, IP66 environmental sealing & vibration resistant internal structure, simplifies steering gear layout and reduces installation workload for marine vessel steering system retrofitting and autopilot overhaul projects.
