Piezoelectronic Buzzers Pin terminal/Lead Without oscillator circuit PS series Issue date: May 2011 All specifications are subject to change without notice. Conformity to RoHS Directive: This means that, in conformity with EU Directive 2002/95/EC, lead, cadmium, mercury, hexavalent chromium, and specific bromine-based flame retardants, PBB and PBDE, have not been used, except for exempted applications.(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.
