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.
