PI (Physik Instrumente) L.P. High-Load Precision Z Stage M-451

The M-451 is a high-load precision Z stage with a 12.5 mm travel range and a self-locking load capacity of 120 N. It is available in variants with an ActiveDrive DC motor, DC gear motor, or 2-phase stepper motor, all featuring roller-bearing-guided wedges for high stiffness and maintenance-free operation. The stage is constructed from anodized aluminum, weighs 5 kg, and operates from -20 to 50 °C. It supports integration with P-500 and PIMars piezo positioning systems, offers design resolutions down to 0.0028 µm depending on the motor type, and includes Hall effect limit and reference switches. Minimum incremental motion ranges from 0.1 to 0.2 µm across variants.
