Version: 1.1.0
PZ259E
P-88x/P-08x Piezo Actuator
Compressive/tensile stress capacity and preload of the P-88x/P-08x
Type of mechanical stress
P-88x/P-08x*
Maximum compressive load capacity
30 MPa
Maximum tensile stress capacity without preload
2 MPa**
Recommended preload for dynamic operation
15 MPa
Maximum preload for constant force
30 MPa
* 1 MPa corresponds to a pressure of 1 N per square millimeter of the base area of the piezo
actuator. Dimensions see data table (p. 47).
** Depends on the strength of the glued connections (p. 26)
10.1.4
Ambient Conditions and Classifications
Pay attention to the following ambient conditions and classifications for the P-88x/P-08x:
Area of application
For indoor use only
Air pressure
500 hPa to 1500 hPa
If you want to operate the P-88x/P-08x outside of the
specified air pressure range, contact our customer
service department (p. 45).
Relative humidity
Maximum relative humidity 55 %
Continuous operation with high static voltage in humid
environments significantly reduces piezo actuator lifetime.
If you want to operate the P-88x/P-08x at a relative
humidity of more than 55 %, contact our customer
service department (p. 45).
