PL0xx/PDxxx Piezo Actuator
5.3
Mounting the PL0xx/PDxxx
PL0xx/PDxxx piezo actuators are glued to metal or ceramic surfaces.
CAUTION
Risk of electric shock and short-circuit from incorrect gluing of the piezo actuator!
The electrodes of the piezo actuator extend to the ceramic end surfaces. If the piezo actuator
is glued to a conductive surface without insulation of the electrodes, the surface can be
electrically live during operation. Touching the surface or conductive parts connected can
result in minor injuries from electric shock. The electronics can be damaged by a short-circuit.
If the piezo actuator is to be glued to a conductive surface, insulate the surface from the
electrodes of the piezo actuator by suitable means:
−
Place a nonconductive insulating layer on the surface
−
Cut the surface to clear the entire area around the electrode
Requirements
You have read and understood the general notes on installation (p. 17).
The PL0xx/PDxxx is discharged (p. 40) and short-circuited (p. 41).
You have read and understood the user information of the manufacturer of the
adhesive.
Tools and accessories
Level surface that is dry, dust-free, and grease-free
Suitable adhesive (e.g., cold-hardening epoxy resin adhesive)
Mounting the PL0xx/PDxxx
1.
Glue the piezo actuator to the surface:
−
Apply the thinnest possible layer of adhesive.
−
During the hardening process, maintain the operating temperature range (p. 53)
specified for the piezo actuator.
−
Observe the temperature expansion coefficients of the materials involved.
2.
Press the piezo actuator until the adhesive has hardened.
