The 9.0mm diameter passive magnetic buzzer is engineered for applications where space, reliability, and cost-efficiency are critical. Operating at a clear 2.37KHz resonant frequency, it delivers a high sound output of 90dB, ensuring your alerts are unmistakably heard.
Compact & Space-Saving: With a minimal profile of just Φ9.0x3.2H (mm), Passive magnetic buzzer fits perfectly into compact PCBs for modern, miniaturized devices.
High Audibility: Produces a loud 90dB sound pressure level at 10cm, ensuring reliable notification in various environments.
Standard Driving Voltage: Designed for 3.6V peak-to-peak operation, making it compatible with common microcontrollers (like Arduino, ESP32) and digital circuits.
Clear & Penetrating Tone: The 2.37KHz frequency provides an attention-grabbing yet non-intrusive alert tone.
Passive Type (No Internal Drive Circuit): Offers maximum flexibility. You control the frequency and tone from your microcontroller, allowing for multi-tone alerts, melodies, or siren sounds.
RoHS & REACH Compliant: Passive magnetic buzzer manufactured with high-quality, lead-free materials meeting international environmental standards.
