Piezo Passive Buzzer – Vertical Mount 2kHz External Drive (22×7×26.5 mm)

Product Description:

The Piezo Passive Buzzer – Vertical Mount (PS-RP2-V27-20) is a high-quality audio transducer designed for generating tones, alerts, and alarms in a wide range of electronic applications. Built with a durable piezoelectric element, this buzzer requires an external square-wave signal for operation, allowing you to create custom tones and frequencies through a microcontroller or driver circuit.

With a resonant frequency of 2kHz and a minimum sound pressure level of 70 dB at 10 cm, this buzzer offers clear and reliable audio output while maintaining extremely low power consumption. Its vertical pin-type lead design ensures easy PCB mounting and is suitable for consumer, industrial, and embedded electronics.
