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 polymer-insulated 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 applications.

* 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.
Vacuum versions to 10-6 hPa are available under the following ordering number: P-844.x0V.
All specifications based on room temperature (22 °C ±3 °C).
