When SERVos are used IN complex OPERATING environments such as robots, models, ETC. Are THERE THESE CONCERNS: gear jamming, servo burning, SERVO being blocked by external FORCE CAUSING damage...... DF has launched a series of servos with clutch function and electronic protection to solve your problems: Clutch function: When the Angle of the servo is changed by external force during normal operation, the servo can automatically reset and continue working through the clutch function, making up for the disadvantage of ordinary servos that are prone to damage when the Angle is changed by external force during operation. Electronic protection: When the servo is blocked for 5 seconds, it automatically cut off the power for protection to prevent the servo from being burned out due to being blocked. Working voltage range: 4.8-6V DC Static current: 8MA AT 6.0V No-load current: 50MA AT 4.8V, 60MA at 6.0V Locked-rotor current: 550MA AT 4.8V, 650MA AT 6.0V Rated torque: 0.32KGFCM AT 4.8V, 0.4KGFCM AT 6.0V Locked-rotor torque: 1.0KGFCM AT4.8V, 1.2KGFCM at 6.0V Operating Angle: 30010 Signal width range: 500-2500S Communication method: PWM Color: Black Material: plastic Package Contents: 1 set * clutch servo motor Only the above package content, other products are not included.
