A high-torque digital servo with all-metal gears, an aluminium shell, and IP67 waterproof rating. Delivers up to 35 kg·cm of stall torque at 7V, making it suitable for demanding robotics applications, multi-joint mechanisms, and outdoor projects where water exposure is a concern.
The MOS-driven DC motor operates quietly with minimal jitter under load. The internal pulse lock function allows the servo to hold position with a single PPM pulse, reducing processor overhead and extending service life. Includes multiple servo horn shapes for different mounting requirements.

Jargon buster
Plain-language definitions for the technical terms used above.
- IP67
- An ingress protection rating meaning the enclosure is dust-tight and can survive temporary immersion in water under specified test conditions. This matters when choosing a sensor for outdoor, wet, or wash-down environments.
- 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.
- ppm
- ppm means parts per million, a common way to express very small gas concentrations in air. For CO₂ sensors, the ppm range tells you what levels the sensor can measure, such as normal indoor air through to poorly ventilated spaces.
- 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.
