Germany ZAHNER ELEKTRIK sensor ZAHNER ELEKTRIK model ZAHNER ELEKTRIK price

ZAHNER ELEKTRIK sensors are measurement feedback devices that operate based on the optical principle of gratings. Grating scales are frequently used in the closed-loop servo systems of CNC machine tools and can be used for detecting linear or angular displacement. The measurement output signal is a digital pulse, characterized by a large detection range, high detection accuracy, and fast response speed. For example, in CNC machine tools, they are often used to detect the coordinates of tools and workpieces to observe and track tool path errors, thereby compensating for the motion errors of the tool. Grating scales are classified according to manufacturing methods and optical principles.
