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.

Jargon buster
Plain-language definitions for the technical terms used above.
- encoder
- A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.
- IP54
- An ingress protection rating meaning the enclosure has limited dust protection and is protected against water splashes from any direction. This matters because it gives a practical indication of how well the product may handle dusty or damp installations.
- kg·cm
- A torque unit often used for hobby servos, meaning how many kilograms of force the servo can hold at a 1 cm arm length. A higher kg·cm rating means the servo can move or hold heavier loads, but power supply current needs may also increase.
- potentiometer
- A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
- Stall torque
- The maximum twisting force a servo can produce when its output is held still and cannot move. It helps you judge whether the servo is strong enough for a robot joint, steering linkage, or other load.
- Torque
- A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
