The Atom Marine Servo is purpose-built to handle wet, high-moisture, and water-spray environments. Using Proton’s FRF (Fiberglass Reinforced Frame) architecture combined with an O-ring sealing system, the Marine model offers enhanced protection against water intrusion while maintaining smooth and accurate control movement.
Our 20% Fiberglass Reinforced Frame (FRF) reduces case distortion and maintains stable alignment between the motor, gear train, and potentiometer. This ensures:
Smooth and consistent servo operation
Improved centering precision
Increased durability, especially under vibration and mechanical load
Unlike the Standard and High Performance models, the Atom Marine Servo includes O-rings integrated into the FRF’s dual U-groove sealing system. When assembled, the upper and lower covers compress the O-rings to create a sealed enclosure—ideal for boats, marine aircraft, seaplanes, and other environments where moisture protection is essential.
