Futaba AJ9DA Series Industrial Servo

Manufacture: Futaba Corporation
Model: AJ9DA Series: AJ9DA41; AJ9DA42; AJ9DA43; AJ9DA44; AJ9DA5; AJ9DA52; AJ9DA53; AJ9DA54
Features
The AJ9DA series is a heavy-duty servo series designed for installation on large fixed-wing UAVs and mobile robots that require even greater torque than conventional servos.
The case, gears, and servo horns are all made of metal as standard. For ease of installation, two types of cables are available: one fixed to the main body and one detachable with a bayonet connector. In addition, by combining high-precision packing and other parts, it meets the dustproof and waterproof standard (IP64).

Control and Communication Standards
Intended for connection to Futaba RC receivers and various other controllers, the controller supports the following standards:
・PWM: PWM signal used in conventional hobby RC servos
・S.BUS: Futaba’s proprietary serial communications protocol for hobby RC servos
・RS485: The same two-way communications protocol as Futaba’s robot command-type servos
Each communication format cannot be used simultaneously.
Position Feedback:
The output voltage changes according to the angle of the output shaft. The angle can be constantly monitored while power is applied.
