Futaba LJ9DA41 Industrial Servov
Manufacturer: Futaba Corporation
Model: LJ9DA41
Features
The LJ9DA41 is a linear motion servo designed for UAS (Unmanned Aerial Systems). The servo integrates a motor, reducer, linear motion mechanism, and control circuit, and communicates with external devices to issue commands and return internal information. It also meets the dustproof and waterproof standards (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.
