B9-12VDC PCB 22mm Magnetic Buzzer 12VDC 80dB Pin Single Tone Black

The B9-12VDC PCB Magnetic Buzzer is a reliable PCB-mount audible signalling device designed for industrial electronics, alarm systems, automation equipment, security devices, and embedded electronic applications. Operating from a 12V DC power supply, this magnetic buzzer produces a clear single-tone output at 3000Hz, providing dependable audible alerts for equipment status, fault indication, and warning notifications.

Delivering an 80dB sound output at 30cm while drawing only 10mA, the B9-12VDC offers an excellent balance of loudness and energy efficiency. Its low current consumption makes it ideal for continuous operation in control systems, electronic instruments, and low-power applications.

The buzzer features a compact 22mm round housing with a 12.5mm height, making it suitable for PCB-mounted installations where reliable audible indication is required. Its pin termination enables secure through-hole mounting and straightforward integration into printed circuit boards during manufacturing or prototyping.

Built using proven magnetic transducer technology, the B9-12VDC PCB delivers consistent sound quality, long service life, and maintenance-free operation. It is an ideal choice for OEM equipment, industrial controls, consumer electronics, medical devices, and DIY electronic projects.
