The B1-12VDC Magnetic Buzzer is a high-output audible signalling device designed for industrial equipment, alarm systems, control panels, automation systems, and general electronic applications. Operating from a 12V DC power supply, this magnetic buzzer produces a powerful 90dB single-tone output at 2800Hz, making it ideal for applications that require clear and attention-grabbing audible alerts.
Unlike piezo buzzers, the magnetic design delivers a strong, consistent tone with excellent sound projection, making it suitable for noisy environments where reliable audible indication is essential. Its robust construction ensures dependable performance and long service life in commercial and industrial installations.
The buzzer features a durable round black housing with a 28mm face diameter and 14.5mm height, making it easy to install in equipment enclosures, alarm devices, and electronic assemblies. Supplied with leadwire connections, it offers simple integration into new designs and replacement applications.
With a low operating current of only 40mA, the B1-12VDC provides efficient operation while delivering a loud 90dB sound output at 30cm. It is well suited for warning systems, fault indication, machine alarms, electronic instruments, and access control equipment.
Whether you're designing industrial machinery, security products, automation systems, or custom electronic projects, the B1-12VDC Magnetic Buzzer delivers reliable, high-volume audible signalling in a compact and durable package.
