The KXG1205C manufactured by Kingstate is an electronic component that combines a buzzer, magnetic plate, and pin to provide an electrical signal with a volume of up to 85dB, powered by a 5V voltage input. This device is often used as an alarm, signaling device, or other notification component. The magnetic plate in the component allows it to be used in alarms, warning systems, and other similar applications. The pin can be connected to a power source which delivers the 5V required to emit the sound. This sound level is adjustable, allowing users to adjust the volume accordingly.
