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 by simply reversing the voltage of the DC motor. All DSZY4 types come standard with two integrated, non-adjustable limit switches directly connected to the DC motor. Overloading of the drive can be managed through separate monitoring and current limiting.
