Frequently Asked Questions
Q: Are these magnetic buzzers compatible with Arduino and Raspberry Pi?
A: Yes! These 3V, 5V, and 12V magnetic buzzers are fully compatible with Arduino, Raspberry Pi, and other common microcontroller platforms. Simply connect the buzzer to the appropriate voltage pin and ground, and use a digital output signal to trigger the continuous beep tone.
Q: What is the difference between the 12095 and 12085 buzzer models in this pack?
A: The 12095 measures 12 × 9.5mm and the 12085 measures 12 × 8.5mm. Both share the same 16Ω impedance and multi-voltage operation, but differ slightly in height, allowing you to choose the best fit for your PCB or enclosure design.
Q: Can I use these buzzers for a continuous alarm signal?
A: Absolutely. These are continuous-beep-tone magnetic buzzers, meaning they emit a steady, uninterrupted audible signal when powered — making them perfect for alarm systems, notification circuits, and any application requiring a persistent alert tone.
