About the wiring method: There are 2 wires in the DC electric push rod motor (12V/24VDC) line connected to the positive and negative poles, the positive and negative poles are interchanged to control the push-out and retraction, and a positive and negative switch can be added to control the expansion and contraction. The faster the speed, the smaller the thrust; the slower the speed, the greater the thrust. The stroke of the push rod motor is not adjustable and has been set at the factory. Power supply DC 12V or 24V. The speed of the push rod can be adjusted by adjusting the voltage of the push rod motor, reducing the voltage and reducing the speed and thrust at the same time. Note that multiple push rods are used at the same time. Due to the tolerance of internal gears, motor and other accessories, the speed is roughly the same, Weight: 1.10231131 pounds, Manufacturer: Xnuiasqe
