The high strain of nanoFaktur’s MPO stack actuators, which are integrated into these levers, allows for smaller components than others on the market with the same displacements. PPa levers are equipped with spark eroded flexures to avoid friction (wear, non-accuracies) and micro-cracks, the presence of which causes reduced lifetimes. The typical lifetime for the nanoFaktur DPa series is of the order of 10 billion full stroke cycles. The DPS versions are equipped with strain-gauge sensors (SGS) full bridges, which enable temperature compensated measurement and control to be achieved.
