Torque-Block^® technical information for customer-specific applications

In a ceramic laminate, separately controllable drive units are mounted by integrated electrode-structuring. Preliminary mechanical stress required for dynamic operation and tensile strain does not interact with operating functions. The simple structure and high reliability are achieved by reduction of load on the outside contact paths as well as absence of complicated eroded flectors. The transformation of the translation into a tilted angle takes place directly in the laminate, and can be read at the end of the lever. Displacement and stiffness can be varied by setting the lever length H, the block height L and the block section. Hardware components of the ase/nvs system or of the unit asy/hyw/e deal with antisymmetric electric control.
