The Primatics PXL43B Series is a small form factor, high precision linear motion stage. A linear motor and linear encoder provide precise positioning travels of 25, 85, 115, 150 millimeters—and anti-creep cage, cross-roller, linear bearings result in smooth, flat, straight motion.



The PXL43B is ideal for use in applications for precision assembly and inspection—a compact size is ideal for space constrained applications. The ironless linear motor and high resolution encoder yields extremely smooth motion for precise scanning applications. Additionally, process corrections are possible thanks to the PXL43B’s industry leading ability to make nanometer-level steps.


A precision linear encoder with index at the center of travel comes standard—forward and reverse limit sensors are also standard. Additionally, multiple resolutions and clock frequencies are available, along with a 1 Vpp analog version. Two PXL43B’s can be directly stacked for an XY configuration with a total height of 86 millimeters, and the smaller PXL33 can be stacked on a PXL43B.


An optional pneumatic counterbalance is available for use in vertical applications—the counterbalance is adjusted for the payload, after installation. Improved accuracy can be achieved with the mapping option—data is provided from laser interferometer measurements to generate position correction information along the entire travel of the stage.
