* Dynamic small-signal stiffness is approx. 50 % higher.
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.
The operating voltage should not exceed 750 V in continuous operation.
Versions without sensor are available under the P-235.x0 and P-235.x0V order numbers.
Vacuum versions are available under the P-235.xxV order numbers.
Specifications for vacuum versions can differ.
