SBT12TMFL

Overview

The SBT12TMFL is an industrial-grade piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a DC voltage range of 9 to 12 volts and produces a sound pressure level of 90 dB. The device features a flange mounting style with a diameter of 44.45 mm. It is designed for use in environments requiring compliance with IEC standards and includes temperature energy specifications. The unit is RoHS compliant and utilizes a stackable design for integration into various audio indicator systems.

Feature Summary

• Industrial-grade construction suitable for demanding operational environments
• Piezoelectric technology providing reliable acoustic output
• Flange mounting configuration for secure panel installation
• Compliance with IEC standards for industrial safety and performance

Applications

• Industrial machinery status indication
• Medical equipment alarm systems
• Transportation vehicle warning signals
• General purpose audio alerting devices

Procurement Notes

Verify the specific suffix and revision code against the manufacturer's current datasheet to ensure compatibility with existing system requirements. Confirm that the 9-12VDC operating range aligns with the target power supply infrastructure. Check for any regional regulatory certifications required for the intended deployment location, such as CE or UL markings, before finalizing procurement decisions.

Selection Notes

Select this component when a robust, industrial-rated audible indicator is required for 9-12VDC systems. The 90 dB output ensures audibility in noisy settings. The flange mount simplifies mechanical integration compared to screw-mount alternatives. Consider the physical dimensions of 44.45 mm diameter when designing enclosure cutouts. Ensure the application does not require variable frequency modulation, as this model provides a fixed tone characteristic.

Part Context

This part belongs to the SBT series of industrial buzzers from Mallory Sonalert. The series is characterized by high durability and standardized form factors for easy replacement. The SBT12TMFL specifically denotes the temperature and energy variant within this lineup, distinguishing it from cardiac or general-purpose models like the SBT12CMFL or SBT12GHFL.

Replacement Considerations

Direct substitutes include the SBT12CMFL for cardiac applications and SBT12GHFL for general purposes, provided the acoustic profile matches the system needs. Verify that the mounting hole diameter and terminal configuration remain compatible during cross-referencing.
