Piezoelectronic Buzzers(without circuit)
PS Series(Pin Terminal/Lead)
Conformity to RoHS Directive
FEATURES
• 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.
APPLICATIONS
Electric ranges, washing machines, computer terminals, various
devices that require speech synthesis output.
