PZ266E
P-88x.x5 Piezo Actuator
NOTICE
Short-circuiting due to complete immersion in a liquid!
Complete immersion of the P-88x.x5 into a liquid can lead to short-circuiting at the stranded
wires. A short-circuit can destroy the P-88x.x5 as well as the electronics connected.
Avoid immersing the stranded wires into liquids. If your application requires complete
immersion of the P-88x.x5 into a liquid, contact our customer service department (p. 37).
NOTICE
Damage to the piezo actuator due to excessive preloading!
Excessive preloading can mechanically depolarize the piezo actuator. Depolarization damages
the piezo actuator.
Only apply preloads that are just as high as necessary.
Do
not
exceed the maximum preload (p. 41).
NOTICE
Destruction of the piezo actuator due to mechanical overload!
Torques, lateral forces, and excessive loads can destroy the piezo actuator.
Do
not
exceed the maximum compressive/tensile stress capacity (p. 41).
Avoid torques and lateral forces on the piezo actuator.
Make sure that the center of load of the moving system is on the motion axis of the piezo
actuator.
Avoid an uneven load distribution by using suitable structures or guide elements (e.g., ball
tips or flexure guides).
Establish contact over as large an area as possible on the end surfaces of the piezo
actuator, and select opposing surfaces with a flatness of only a few micrometers. Minor
unevenness can be compensated by full-surface gluing, for example.
NOTICE
Damage to the piezo actuator due to sideways mounting!
Sideways mounting of the housing leads to deformation of the metal bellows of the piezo
actuator and restricts its motion. The piezo actuator can be damaged when mounting the
housing sideways.
Do
not
mount the housing of the piezo actuator sideways.
NOTICE
Damage due to tensile stress on the stranded wires of the piezo actuator!
Impermissible forces on the stranded wires can damage the piezo actuator.
Avoid tensile stress on the stranded wires of the piezo actuator.
