Dynamixel-P Servomotor H42P-020-S300-R: Compact and Powerful RS485 Servomotor

The Dynamixel-P servomotor H42P-020-S300-R is an all-in-one actuator designed to offer high performance through the RS485 multidrop communication bus. This servo motor is ideal for those looking for a compact, yet highly efficient device.

With five operating modes, including extended position control and PWM control, this servo motor enables optimal acceleration and braking control in mobile robots. Despite having less power than the 100 or 200 W models, the H42P-020-S300-R offers exceptional torque, precision and speed, thanks to a resolution of 607,500 pulses per revolution and a reduction ratio of more than 300:1. The servo motor weighs only 340 g, making it easily adaptable to various configurations in your robotic systems.

Reliability and Accuracy of the Dynamixel-P Range

The Dynamixel-P series has revolutionized servo motor performance by emphasizing reliability and resolution. Each model enables superior motion accuracy and remarkable response time while reducing noise and the risk of overheating. The JST connectors have been improved for durability and ease of use, while the programmable control board has been adapted to include all the advanced functions of the X-Series devices.
