(1/7) Conformity to RoHS Directive Piezoelectronic Buzzers(without circuit) PS Series(Pin Terminal/Lead) FEATURES APPLICATIONS  The PS series are high-performance buzzers that employ Electric ranges, washing machines, computer terminals, various unimorph piezoelectric elements and are designed for easy devices that require speech synthesis output. incorporation into various circuits.  They feature extremely low power consumption in comparison to SOUND MEASURING METHOD electromagnetic units. Piezoelectric Standard buzzer microphone AMP Filter (A curve)  Because these buzzers are designed for external excitation, the DC power Driver supply circuit Measuring same part can serve as both a musical tone oscillator and a Testing input voltage distance Recorder 10cm buzzer. Anechoic chamber  They can be used with automated inserters. Moisture-resistant Frequency counter models are also available.  The lead wire type(PS1550L40N) with both-sided adhesive tape installed easily is prepared.

Piezoelectric buzzer  Do not supply any voltage higher than applicable to the piezo- electric buzzer. C-MOS, etc R Tr (  Do not use the piezoelectric buzzer outdoors. It is designed for Suitable ) C1815 indoor use. If the piezoelectric buzzer has to be used outdoors, GND provide it with waterproofing measures; it will not operate ∗ normally if subjected to moisture. Resistor to do charging and discharging to a piezoelectric element (Value of about 1kΩ is good efficiency).  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 containg 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. 005-03 / 20070417 / ef532_ps.fm ∗ R
