Our axis controllers use the digital signals for positioning and counting. Positioning accuracies of 0,01 mm, 1 µm, or 0,1 µm are possible. Systems with resolutions of 0,1 µm have been supplied for: Gene technology - work with microscope Extruder - foil thickness measuring Heavy Ion Research Institute GSI: positioning of sensors   back to product overview ROTRA Your partner for automation since 1987
