Overview
The SBT12DMFL is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc., designed for industrial applications. It features a flange mounting style with a diameter of 44.45mm. The device operates within a voltage range of 9 to 12VDC and produces a sound pressure level of 90dB. It is rated for an operating temperature range of -30°C to +65°C. The component is RoHS compliant and classified as an industrial-grade audio indicator.
Feature Summary
- Industrial-grade construction suitable for demanding environments
- Piezoelectric transducer technology for reliable acoustic output
- Flange mounting design for secure panel installation
Applications
- General industrial alarm systems
- Equipment status indication in manufacturing
- Safety warning devices in heavy machinery
Procurement Notes
Verify the specific datasheet revision and mechanical drawings before integration, as industrial components may have variant specifications. Confirm that the 9-12VDC input matches the system power supply architecture. Ensure the 44.45mm flange dimension aligns with the enclosure cutout requirements. Check for any regional compliance certifications required for the target deployment market.
Selection Notes
Select this model when a robust, high-decibel audible alert is required for industrial settings. The flange mount provides stability compared to through-hole options. Consider the 90dB output sufficient for noisy factory floors. Verify thermal tolerance against the operational environment, noting the -30°C to +65°C range. Compare against other SBT series variants if different frequencies or voltages are needed.
Part Context
This part belongs to the SBT series of industrial buzzers from Mallory Sonalert. These components are distinct from medical or consumer-grade indicators due to their ruggedized housing and higher acoustic output. The series typically includes variants for specific applications like cardiac or perfusion monitoring, but the DMFL suffix denotes a general industrial use case with flange mounting.
