FEETECH SM120BL Servo Motor, 24V RS485 Serial, 120kg.cm Torque, Brushless, Steel Gears, 360° Range, Aluminium 7075

Overview

The FEETECH SM120BL Servo Motor is a 24V serial-control RS485 actuator designed for robotics and automation applications. It provides peak stall torque of 120kg.cm at 24V and a no-load speed of 0.2sec/60degree (50RPM). The unit features a brushless motor, steel gears with a 232:1 ratio, Aluminium (7075) case, and 2 ball bearings. It supports 360° operation (when 0~4095) with 12-bit magnetic position sensing and comprehensive feedback including load, position, speed, input voltage, current, and temperature.
