Which RS485 Smart Servo Should I Choose?

Choose SM-260B-C001 (24V, 260 kg·cm) if you need:

Maximum torque for heavy robotic joints, industrial manipulators, humanoid robots
High-load actuation where torque headroom matters most
Robust performance for demanding mechanical assemblies

Choose SM-120B-C001 (24V, 120 kg·cm) if you need:

a balanced solution for robot arms, automation equipment, research platforms
strong torque without over-sizing the actuator
a versatile 24V smart servo for general industrial integration

Choose SM-105B-C001 (12V, 150 kg·cm) if you need:

a powerful RS485 actuator for 12V systems (mobile platforms, compact automation)
high torque on lower-voltage architectures
efficient integration into battery-based robotics and transport systems

Shared features across all RS485 smart servos

All models support:

RS485 serial bus communication (addressable multi-servo networking)
brushless motor technology, steel gearbox, aluminium housing
0–360° programmable angle control + multi-turn operation mode
telemetry feedback: position, speed, voltage, current, temperature, load
soft start/stop, programmable acceleration/deceleration
overload and over-current protection

Support & confidence for bulk orders

We supply genuine Feetech smart servos with manufacturer warranty and provide pre-sale integration guidance plus after-sales support—so it’s safe to purchase for professional and institutional deployments.

Tip: For system planning, compare voltage architecture first (12V vs 24V), then select torque capacity based on load, lever arm length, and safety margin.
