BLA21-12R3-C01 (Type C: Compact and Lightweight Model)

Features

This industrial servo is the successor to the RS405CB, offering significantly improved functionality, performance, and durability.

Despite its compact dimensions of approximately 41 mm × 33 mm × 42 mm (1.59 in × 1.30 in × 1.65 in)  and weight of only 67 g, the servo delivers a maximum torque of 4.9 N·m, offering a high power-to-weight ratio compared with general-purpose FA servos.
A complete redesign has improved maximum output by approximately 2.6 times and increased durability by more than two times compared with the previous model.*
*Based on in-house testing conditions.

In addition to supporting conventional PWM and RS485 communication, the servo also supports the newly developed CM.BUS* control protocol. (*Patent pending)
By utilizing CM.BUS, the servo can read and write only predefined data within the system, minimizing the amount of data required for control and status acquisition. This significantly improves processing speed and throughput.
