The linear electric cylinder DSZY4 is equipped with a trapezoidal lead screw (ACME screw). This electric cylinder is a small, compact, and lightweight DC linear drive with high forces. An integrated diode circuit allows for quick direction reversal through simple voltage polarity reversal of the DC motor. By default, all DSZY4 types come with two integrated, directly connected, non-adjustable limit switches. Overloading of the drive can be managed through separate monitoring and current limiting. Application areas include vehicle construction, lifting tables, satellite dish adjustment, hospital beds, roof windows, roof adjustments in greenhouses, mobile traffic signs, test benches such as accelerator pedal adjustments, photovoltaic systems (tracking), flight simulators, flap adjustments on ship engines, locking mechanisms, and robotics.
