AJ9DA Series

Features

The AJ9DA Series is a heavy-duty servo series designed for applications requiring higher torque than conventional servos, including large fixed-wing UAVs and mobile robots.

The case, gears, and servo horn are all made of metal. To improve installation flexibility, two cable types are available: a fixed cable type and a detachable cable type using a bayonet connector. In addition, highly precise assembly of sealing components provides dust and water protection compliant with IP64 standards.

Operation Manual icon_pdf.gifAJ9DA Series Operation Manual
  • Control and Communication Standards 
    To support connection with Futaba RC receivers and various other controllers, the following communication standards are supported:
    • PWM: PWM signals used in conventional hobby RC servos
    • S.BUS: Futaba’s proprietary serial communication protocol for hobby RC servos
    • RS485: Bidirectional communication protocol compatible with Futaba command-type servos for robotic applications
    Please note that these communication methods cannot be used simultaneously.

Position Feedback
The output voltage varies according to the angle of the output shaft, enabling continuous angle monitoring during operation.
