Description
The high strain capability of nanoFaktur’s MPO stack actuators integrated into these levers results the smallest components on the market with such large displacements. PPa levers are equipped with spark eroded flexures to avoid friction and micro-cracks, avoiding reduced lifetimes. These moving platforms from nanoFaktur are guided in parallel under complete control. The PPS versions are equipped with strain gauge sensors which enable temperature compensated measurement and control to be achieved.
