This is an extraordinary water-resistant digital servo with formidable torque, possessing a torque capacity of 20kg and a controllable angle of 180 degrees. It exhibits enhanced linear motion and features an internal configuration of copper gears, with the gear axis thickened to an optimized 2.0 center distance. The dual ball bearing design ensures impeccable performance, while the aluminum casing promotes superior heat dissipation, thereby extending the lifespan.

20KG 180° Metal Waterproof Servo

Additionally, this servo is equipped with electronic and temperature protections, ensuring a safer user experience. In the event of a servo lock-up, it automatically triggers a protective torque output when the torque exceeds the overload capacity for a continuous period of 8 seconds. Moreover, should the servo's temperature surpass 70 degrees, it ceases torque output, only to resume once the temperature drops below 70 degrees.

Quality Material of Metal Waterproof Servo

To enhance its water resistance, the servo's joints are fortified with waterproof gaskets, and the circuit board is coated with a waterproof varnish. Both the motor and the potentiometer are sealed with a specialized adhesive. These measures contribute to the servo's exceptional waterproof capabilities. Moreover, this servo is accompanied by a selection of different-shaped servo horns, enabling its application in a wider range of environments.
