Ambient Conditions And Classifications - PI P-88 Series User Manual

10 Technical Data
Compressive/tensile stress capacity and preload of the P-88x/P-08x
Type of mechanical stress
Maximum compressive load capacity
Maximum tensile stress capacity without preload
Recommended preload for dynamic operation
Maximum preload for constant force
* 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)

Ambient Conditions and Classifications

Pay attention to the following ambient conditions and classifications for the P-88x/P-08x:
Area of application
Air pressure
Relative humidity
Operating temperature
Storage temperature
Transport temperature
Overvoltage category
Degree of pollution
The P-88x/P-08x is intended for installation in devices that fulfill the following classifications:
Protection class
Degree of protection according
to IEC 60529
52 Version: 1.1.0
For indoor use only
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).
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).
 Pay attention to the information on service life, which
can be found here:
