Features Electric putter, also known as push rod motor, electric cylinder and linear actuator. The electric putter is an electric drive that converts the motor's rotational motion into a straight reciprocating motion of the push rod. Can be used in a variety of simple or complex process as the implementation of mechanical use, in order to achieve long-range control, centralized control or automatic control. Main use: electric medical bed, electric sofa, electric stand lift rod, industrial electric lift system, camera frame, video machine, wedding system. Low noise design, noise level is ≤ 42dB.Inside set a stroke switch.Can be matched with wire or remote control.
