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.

* Electrical capacitance: Measured at 1 V_pp, 1 kHz, RT, tolerance ±20 %.

** Resonant frequency: Measured at 1 V_pp, unloaded.

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.

All specifications depend on actual clamping conditions and mechanical load applied.

All specifications based on room temperature (22 °C ±3 °C).

Different specifications on request.
