* 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 connector: LEMO FFA.00.250. RG 178 coaxial cable, 1 m.
Housing / tip material: Stainless steel.
Vacuum versions to 10
-6
hPa are available under the order number P-844.x0V.
All specifications based on room temperature (22 °C ±3 °C).
Specifications for vacuum versions can differ.
