Futaba BLA21-12R3-C01 C Type Industrial Servo

Manufacture: Futaba Corporation
Model: BLA21-12R3-C01
Features
This industrial servo is built on the foundation of the discontinued RS405CB command type servo, offering significantly enhanced functionality, performance, and durability.
Despite its small and lightweight design—measuring approximately 41mm x 33mm x 42mm and weighing only 67g—the servo delivers a maximum torque of 4.9 N·m, achieving a higher power-to-weight ratio than typical FA servos. The comprehensive redesign has resulted in a maximum output that is about 2.6 times higher, with durability more than double that of traditional products (* based on our company’s test conditions).
In addition to supporting conventional PWM and RS485 communication, the servo now also supports the new CM.BUS control protocol (patent pending). Using CM.BUS allows users to write/read only the specified data stored within the servo, significantly reducing the amount of data needed for control and information acquisition, thus greatly improving processing speed and throughput.
