Active Buzzer 3V-24V - Continuous

A simple buzzer to eg. indicate errors with an Arduino. With this active buzzer one only has to offer voltage, no frequency. So that's 3 to put 24V on the buzzer, and he then beeps! If you do not have any (for noise) pins anymore, this buzzer probably also comes in handy! This can be easily mounted on a breadboard or experimental PCB.

Specifications:

• Input voltage: 3V-24V
• Peak current: 30mA (so use a transistor, eg. 2N3904, when you want it on connected to an Arduino)
• Dimensions: 48 x 30 x 15 mm
• Inside sizes of mounting holes: 3.2mm diameter, 4.6mm high
• Length of wires: 11 cm
• Buzzer sound: BEEP (continuous)
