Preloaded Piezo Actuators For High Loads and Forces, with Position Sensor P-845  Outstanding lifetime due to PICMA® piezo actuators  Travel range to 90 µm  Push force capacity to 3000 N  Pull force capacity to 700 N  µs response time  Subnanometer resolution  Vacuum versions, optional water-resistant housing Application fields Static and dynamic precision positioning Fiber positioning Laser tuning Nanotechnology Outstanding lifetime thanks to PICMA® piezo actuators The patented PICMA® piezo actuators are all-ceramic insulated. This protects them against humidity and failure resulting from an increase in leakage current. PICMA® actuators offer an up to ten times longer lifetime than conventional polymerinsulated actuators. 100 billion cycles without a single failure are proven. Suitable for sophisticated vacuum applications Piezo actuators do not require lubrication and do not cause abrasion. The all-ceramic isolated PICMA® actuators also do not require polymer isolation and are therefore ideal for vacuum
