PZ265E
PL0xx/PDxxx Piezo Actuator
5.2
Connecting a Piezo Actuator with Stranded Wires (Only Models
Without Stranded Wires)
The electrodes can make contact in one of the following ways:
Soldering the stranded wires (p. 22)
Gluing the stranded wires (p. 24)
If your application permits it, we recommend using models that already have stranded wires.
5.2.1
Soldering Stranded Wires to a Piezo Actuator (Only Models Without
Stranded Wires)
NOTICE
Damage due to overheating of the piezo actuator during soldering!
Heat spreading from the piezo actuator that rises above the Curie temperature leads to
depolarization of the piezo ceramic. Depolarization can damage the piezo ceramic. Long and
repeated soldering processes can cause damage to the electrode.
The soldering temperature should not be any higher than necessary (max. 350 °C).
Make sure that the soldering time does
not
exceed one second.
Allow the solder point to cool down before resoldering.
NOTICE
Damage due to mechanical stress on the solder connection!
Mechanical stress on the solder connection due to moved stranded wires can damage the
piezo actuator.
Avoid tensile stress and shear forces on the solder connections.
INFORMATION
The electrode marking is shown in the product view (p. 10).
Use a red stranded wire for the voltage connection (+).
Use a black stranded wire for ground (-).
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).
