Large Enclosed Piezo Element w/Wires
We have ✅ 7 available of the AF-1739 in our Sydney warehouse.
This large enclosed piezo element (30 mm diameter) converts vibration to voltage and voltage to vibration, making it useful both as a buzzer for generating tones and as a sensor for detecting knocks and impacts. The enclosed housing includes mounting holes for easy attachment to panels, enclosures, or drum pads.
Rated for up to 12 Vpp, it also works well with 3.3 V or 5 V square waves and is plenty loud for alert and notification applications. Pre-attached wires are suitable for breadboard use, though they may be too thin for direct insertion into Arduino socket headers.
