This high-torque waterproof digital servo delivers up to 35 kg·cm of torque at 7.4V and features a 12-bit magnetic encoder for precise absolute position control across a full 360° range. Built for demanding robotics and automation applications, it combines reinforced steel gears, dual ball bearings, and an aluminium housing for durability and efficient heat dissipation.

The servo includes electronic lock-up protection (triggers after 4 seconds of overload) and thermal protection (ceases output above 70°C, resumes once cooled). Waterproof gaskets at all joints, varnish-coated circuitry, and sealed motor and potentiometer provide IP54 splash-proof protection for outdoor and wet environments.
