Product Description

**This product may require a 2-4 week lead time for delivery.**


  • DYNAMIXEL is a robot-exclusive smart actuator with a fully integrated DC Motor + Controller + Driver + Sensor + Reduction Gear + Network in one DC servo module.
  • DYNAMIXEL-P Series implements removable reduction cycloid gears, resulting in high precision and impact resistance.
  • Torque control based on current sensing
  • Position, Torque, and Speed-based command
  • High resolution with a combination of Incremental Encoder and Contactless Absolute Encoder
  • Full metal housing for high durability
  • Can be used to make a full-size manipulator, pan tilt, humanoid, etc.

[DYNAMIXEL PRO -> P] Upgrade Details

  • Improved design and JST connectors applied
  • Improved dirt inflow and leakage
  • Improved control table (Supports X Series functions) 
  • Enhanced control performance such as responsiveness and resolution
  • Enhanced communication responsiveness
  • Improved heat, noise, and durability


Performance Comparison


  • The operational voltage is different from other DYNAMIXEL series (Operational voltage: 24V).
  • Depending on the number of units used, it is recommended to use a separate power supply.
  • JST 4Pin connector is applied for communication.
  • The 42 series uses the same hinge frames.(FRP42-H110/120)
