Overview
The SITO DRIVE TA-40 rotary actuator is offered with 50 or 100 transmission-ratio options and a without-brake selection. Both versions use CAN 2.0B communication at 1 Mbps and accept a 10–60 V supply (24 V recommended). Ratio selection changes torque, speed, repeat positioning accuracy, power, and without-brake weight, allowing buyers to match the actuator to motion-system requirements.
Features
- Face-mounting installation method
- 40 mm diameter, 55.55 mm length, and 6 mm hollow bore
- CAN 2.0B communication with 1 Mbps baud rate
- 10–60 V supply voltage; 24 V recommended
- V1 version model and IP54 grade

Applications
TA-series application material lists humanoid robots, robotic arms, exoskeletons, quadruped robots, AGV vehicles, and ARU robots. These are family-level examples rather than verified TA-40 compatibility. For a motion system requiring a face-mounted CAN 2.0B actuator, compare the ratio-specific torque, speed, and positioning-accuracy values against the system requirements.
