Description
The DFROBOT High Torque Waterproof Digital Servo is engineered for durability and power, making it ideal for robotics, RC vehicles, automation, and industrial applications. With a torque capacity of 20kg and a 180° controllable angle, it delivers precise motion control under demanding conditions.
Built with high-strength copper gears, a reinforced 2.0mm gear axis, and a dual ball bearing design, this servo ensures smooth, reliable performance with enhanced linear motion. The aluminum alloy casing improves heat dissipation, extending its service life, while the IP54 water-resistant rating provides protection against dust and splashes, allowing it to perform in tough environments.
