## Description

2-axis servo motor for Arduino and automation projects, offers precise 0-270 degree rotation and high torque up to 20 kg.cm. Operates at 4.8-8.4V with PWM control, has metal gears and internal aluminum alloy housing for reliability and better heat dissipation, splash-proof construction for use in harsh environments.
Performance servo motor with 2 axes, TD-7120MG, compatible with Arduino and other development boards capable of generating PWM signal.
The two axes are opposite, one being the one that performs the rotation, the opposite one is the support.
It supports a rotation between 0 and 270 degrees and a maximum power of 20Kg/cm.
The gears are made of metal and the inner case is made of aluminum alloy to improve heat dissipation and reliability.
The servo motor is water resistant, having the input wires and the gear isolated. From the tests carried out, we had no problems with its continuous operation immersed in water at 10cm depth for 30 minutes, but we recommend avoiding the operation of the servomotor submerged because, as the product does not have an official water resistance rating, damage caused by liquids is not covered by the warranty .
Important: Used with RC remote controls, if they are not capable of the PWM signal required by the servo motor, you may not have the full 0-270 degree rotation angle available.
