XLA-1 Closed-loop series
Fast and compact linear actuator
The XLA closed-loop micro linear actuators are world class in terms of weight, size and precision. The actuator is driven by the Crossfixx™ ultrasonic piezo motor, allowing an extremely compact design, variable speeds up to 200 mm/s and a total weight of less than 6 gram! The XLA-1 Closed-loop has an integrated encoder with a 1250, 312 or 78 nm resolution. Two cable positions are possible (top or side) and a wide range of rod lengths is available, allowing stroke lengths from 5 mm to 185 mm!

Controller/software
In closed-loop configuration, the XLA-1 series actuators are compatible with all Xeryon controllers. Controlling of the stage is done with:
· easy-to-use Windows interface
· LabVIEW interface program (compiled program or source)
· MATLAB interface script
· C++ and Python libraries
