The magnetic buzzer uses the action of the coil in the buzzer to sound.It mainly consists of an oscillator, a coil, a magnet, a vibrating disk and a housing. After the power is turned on, the current of the audio signal generated by the oscillator passes through the electromagnetic coil, so that the electromagnetic coil generates a magnetic field. The vibrating disc periodically vibrates the sound under the interaction of the electromagnetic coil and the magnet.In this case it has 3 cables. Depending on how we polarize it, we get a continuous sound or an intermittent sound • Working voltage range: 4.0..9.0Vdc • Nominal voltage: 6Vdc • Consumption: 35..10mA • Frequency: 2800Hz ± 200Hz • Tones: continuous / intermittent • Working temperature: - 20º .. + 60ºC • Terminals: AWG28 • Case: ABS • Weight: 10gr
