Active DC Piezo Buzzers, 3–24V, Pack of 5

Give an electronics project an audible alert with this five-piece pack of active piezo buzzers. The continuous tone provides a simple sound output when correctly powered.

• ✅ Make an event audible - a powered buzzer can signal a project status or alert.
• ✅ Build more than one prototype - five units give you parts for several circuits.
• ✅ Plan a compact installation - the approximately 23 mm body fits small project layouts.

Turn a Circuit Signal into an Audible Alert

Use a buzzer as the sound-producing component in a hobby circuit, indicator or prototype. An active sounder produces its tone from a suitable DC supply, while your circuit determines when it is powered.

Check voltage, polarity and the required driver arrangement before connecting it. These are individual electronic components rather than a complete alarm system, and they need installation within your own project.
