LJ9DA41
Features
The LJ9DA41 is a linear motion servo designed for UAS (Unmanned Aerial System) applications and related systems.
The servo integrates a motor, gearbox, linear drive mechanism, and control circuitry into a single unit.
It can receive operation commands and return internal status information through external communication. The unit also supports dust and water protection compliant with IP64 standards.

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