The SMB12 Mechanical Buzzer is a reliable 12V DC self-driven mechanical buzzer designed for audible signalling in industrial equipment, control panels, alarm systems, security devices, and OEM electronic products. Producing a clear 80dB sound output at 20cm, it provides dependable audible alerts for equipment status, fault indication, and warning notifications.
Operating from a 12V DC supply with a low current consumption of 30mA, the SMB12 features an integrated drive mechanism that generates a 400Hz tone without requiring an external oscillator or driver circuit. This makes installation quick and straightforward for a wide range of electronic and electrical applications.
The buzzer is housed in a durable rectangular white enclosure measuring 22.5 × 16 × 14.5mm, with flexible lead wire termination for convenient installation in control cabinets, automation equipment, electrical panels, and custom electronic assemblies.
Designed for long-term reliability and consistent performance, the SMB12 Mechanical Buzzer is suitable for commercial, industrial, and educational applications requiring dependable audible indication.
