Piezoelectronic Buzzers(without circuit)
PS Series(Pin Terminal/Lead)
Conformity to RoHS Directive
FEATURES
APPLICATIONS
• The PS series are high-performance buzzers that employ
unimorph piezoelectric elements and are designed for easy
incorporation into various circuits.
• They feature extremely low power consumption in comparison to
electromagnetic units.
• Because these buzzers are designed for external excitation, the
same part can serve as both a musical tone oscillator and a
buzzer.
• They can be used with automated inserters. Moisture-resistant
models are also available.
• The lead wire type(PS1550L40N) with both-sided adhesive tape
installed easily is prepared.
Electric ranges, washing machines, computer terminals, various
devices that require speech synthesis output.

PRECAUTIONS FOR USE
• Do not apply DC bias to the piezoelectric buzzer; otherwise
insulation resistance may become low and affect the
performance.
• Do not supply any voltage higher than applicable to the piezoelectric buzzer.
• Do not use the piezoelectric buzzer outdoors. It is designed for
indoor use. If the piezoelectric buzzer has to be used outdoors,
provide it with waterproofing measures; it will not operate
normally if subjected to moisture.
• Do not wash the piezoelectric buzzer with solvent or allow gas to
enter it while washing; any solvent that enters it may stay inside
a long time and damage it.
• A piezoelectric ceramic material of approximately 100µm thick is
used in the sound generator of the buzzer. Do not press the
sound generator through the sound release hole otherwise the
ceramic material may break. Do not stack the piezoelectric
buzzers without packing.
• Do not apply any mechanical force to the piezoelectric buzzer;
otherwise the case may deform and result in improper operation.
• Do not place any shielding material or the like just in front of the
sound release hole of the buzzer; otherwise the sound pressure
may vary and result in unstable buzzer operation. Make sure that
the buzzer is not affected by a standing wave or the like.
• Be sure to solder the buzzer terminal at 350°C max.(80W
max.)(soldering iron trip) within 5 seconds using a solder
C-MOS, etc

containing silver.
• Avoid using the piezoelectric buzzer for a long time where any
corrosive gas (H2S, etc.) exists; otherwise the parts or sound
generator may corroded and result in improper operation.
• Be careful not to drop the piezoelectric buzzer.
• All specifications are subject to change without notice.
