Unique-Bargains 5pcs DC 3-24V Piezo Alarm Buzzer

Five-piece alarm buzzer kit

This pack contains five active piezo buzzers designed for DC circuits from 3 V to 24 V. Each unit has a plastic housing measuring 23 mm in diameter and 10 mm in height with 10 cm wire leads. The set suits hobbyists, technicians and OEM assemblers who need multiple audible indicators for prototyping or production.

Sustained-load behaviour

Under continuous voltage the piezo element maintains a steady tone without the current spikes typical of electromagnetic alternatives. Low power draw keeps heat negligible during extended operation, and the sealed plastic body resists dust ingress in industrial cabinets. Wire leads remain flexible after repeated thermal cycles.

Voltage-range selector

The 3 V to 24 V rating is the single figure that decides fit; any supply outside this window will either silence the buzzer or risk permanent damage. No other specification in the data overrides this limit.
