Preloaded Piezo Actuators Compact Actuators for High Loads and Forces P-840  Outstanding lifetime due to PICMA® piezo actuators  Travel range to 90 µm  Compact housing  Push force capacity to 1000 N  Pull force capacity to 50 N  µs response time  Subnanometer resolution  Versions with ball tip, vacuum versions 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 vacu

Static large-signal stiffness** Push force capacity Pull force capacity Electrical capacitance Resonant frequency f0 (no load) Operating temperature range Mass without cable Recommended electronics * The resolution of the system is only limited by the noise of the amplifier and measuring technology because PI piezo actuators are free of friction. ** Dynamic small-signal stiffness is approx. 30 % higher. Voltage connection: LEMO FFA.00.250. Coaxial cable RG 178, 1 m. Housing / tip material: Stainless steel. -6 Vacuum versions to 10 hPa are available under the order number P-840.xxV.
