High Torque Waterproof Digital Servo with Magnetic Encoder (25KG, 360°, IP54)

This is an exceptionally high-torque, waterproof digital servo equipped with a magnetic encoder, delivering a maximum torque of 25kg/cm. It features a 12-bit high-precision magnetic encoder sensor that allows for precise and absolute control within a 360-degree range, ensuring unmatched accuracy. With its enhanced linear motion capabilities, this servo offers superior performance.

Internally, it employs a gear system comprised of reinforced steel gears with an optimized center distance of 2.0, ensuring both durability and improved power transmission. The servo also incorporates a dual ball bearing design for smoother operation and includes an aluminum housing that boosts its heat dissipation abilities, thereby extending its lifespan.

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 4 seconds. Moreover, should the servo's temperature surpass 70 degrees, it ceases torque output, only to resume once the temperature drops below 70 degrees.

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.
