Sitex SP120 Autopilot Rudder Feedback No Drive

The SI-TEX Sitex SP120 Autopilot Rudder Feedback No Drive is a marine autopilot rudder feedback sensor designed for vessels requiring closed-loop steering control without direct drive integration. This feedback unit operates as a standalone component within integrated autopilot systems, providing real-time rudder position data to maintain precise course correction. Built for commercial and tactical maritime operations, this sensor eliminates the complexity of full autopilot drive systems while delivering the rudder feedback essential for accurate autopilot function.

The SP120 utilizes feedback-only architecture, transmitting rudder angle signals back to the autopilot controller without providing motor drive output—a critical distinction for vessels with independent or hydraulic steering systems. Weighing 3.25 lbs, this compact sensor integrates easily into existing autopilot installations where the steering actuator is managed separately. The no-drive configuration reduces power consumption and eliminates redundant motor control, making it ideal for systems already equipped with robust steering mechanisms or those requiring modular component replacement without full system overhaul.

Operators managing tactical or commercial marine platforms benefit from this sensor's reliability in maintaining autopilot accuracy across extended operations. Installation requires integration with existing autopilot controllers and rudder position transducers—professional marine technicians should confirm compatibility with your specific autopilot model before ordering. The SP120 is particularly valuable for vessels where steering systems have been upgraded or repaired independently, offering a cost-effective feedback solution that preserves existing drive infrastructure while restoring full autopilot capability.
