NANO FAKTUR >> Piezo-Actuators

DPa Double Lever-Actuators

The double-levers DPO and DPS are driven by our superior MPO piezo-actuators. The large strain of these stacks is allowing for more compact shapes at the same displacements. The guidances and joints are made of electro-eroded flexures, which are avoiding friction, wear and micro-cracks. The life-times are in the order of 10 billion full-stroke cycles. The connection wires are not being moved, when the actuators are driven.

The versions DPS are equipped with strain-gage (SGS) full-bridges. These sensors guarantee temperature-compensated measuring and controlling of motion.

PPa Parallel Lever-Actuators

PPO and PPS levers are driven by our superior MPO stack-actuators. The high strain of these stacks allows for smaller constructions at given displacements. Our levers are equipped with electro-eroded flexures. This is a difference to other suppliers. Flexures avoid friction (wear, non-accuracies) and also micro-cracks, which would reduce life-time. The moving platforms (10×13 mm) are being guided in parallel. Thus PPa can be used for shifting mirrors for example.

PPS are equipped with strain-gage (SGS) full-bridges, which care for temperature-compensated measuring and controlling positions.

HPa Piezo Direct-Drives

Features

●Up to 40% shorter at same strokes
●Housing is only 12 mm in diameter
●Isolated connections (current not flowing back via shielding)
●Versions with 60 V maximum Voltage available
●Optional strain-gauges (versions HPS) and controllers
●Versions for high-dynamic use available
●Hermetically sealed, waterproof, encapsulations possible

MPO Piezo Stacks

Features

●Large strain of ca. 1.5‰ at 0 to 150 V
●>2‰strain in the extended voltage-range of -45 to 180 V
●Consequently laminated structure and monolithic sintering guarantee best possible dimensional tolerances and straightness of motion
●Avoiding of micro-cracks and the pillow-effect at simultaneous insulation-safety is achieved by µm-precise definition of the electrodes (drawn back) in combination with an elastic isolation
