Dynamixel XH430-W350-T Servo

Dynamixel XH430-W350-T servo: cost-effective, ultra-efficient and highly controllable

Like all the servos in the Robotis XH series (the H standing for “High performance”), the XH430-W350-T model stands out from the crowd for its numerous features, including:

• Many mounting options thanks to a wide range of compatible hardware, and 3 wiring options to reduce friction and tear when the servo’s on;
• Full and precise control over velocity, position, trajectory, torque, consumption, power, PWM... In short, everything you’ll need;
• Access to an advanced control table compatible with Mac, Windows and Linux, via a USB2Dynamixel stick or a compatible controller;
• A case in engineering plastic and aluminium that helps prevent damage from overheating.

A Robotis servo designed for your most ambitious projects

Humanoid robot, articulated robotic arm, sophisticated remote-controlled vehicle, mobile robot with numerous applications... This Dynamixel servomotor from the XH series will satisfy all your needs. An equivalent servo is also available in an RS485 version.
