L-731 Precision XY Stage

High Travel Accuracy and Stability

L-731 Precision XY Stage

Product Description Specifications Downloads Quote / Order

Noncontact optical encoders measure the position directly at the platform with the greatest accuracy. Nonlinearity, mechanical play or elastic deformation have no influence on the measurement. Optical limit and reference switches. Further travel ranges on request.

With crossed roller guides, the point contact of the balls in ball guides is replaced by line contact of the hardened rollers. Consequently, they are considerably stiffer and need less preload, which reduces friction and allows smoother running. Crossed roller guides are also distinguished by high guiding accuracy and load capacity. Force-guided rolling element cages prevent cage creep.

2-phase stepper motor for high torque even at low velocities and higher resolution
DC motor for high velocity constancy, low vibration, and high velocities
