SBT12GLFL

Overview

The SBT12GLFL is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc., designed for industrial applications. It operates on a DC input voltage range of 9-12VDC and produces a sound pressure level of 90dB. The device features an internal driver circuit and utilizes a flange mounting style with a diameter of 44.45mm. It complies with RoHS standards and holds cUL recognition under IEC60601-1-8 AMD2:2020 for low priority medical alarms.

Feature Summary

• Piezoelectric technology with integrated internal driver circuitry
• Industrial-grade construction suitable for demanding environments
• Flange mounting design for secure panel installation
• Compliance with IEC60601-1-8 standards for medical alarm classification

Applications

• Low priority medical alarms in healthcare facilities
• General industrial audio indicators
• Equipment status signaling in manufacturing systems

Procurement Notes

Verify the specific acoustic output and frequency response against project requirements, as datasheets may vary by revision. Confirm that the flange mounting dimensions match the enclosure cutout specifications. Ensure the 9-12VDC operating range aligns with the system power supply. Check for current IEC60601-1-8 compliance documentation if used in regulated medical equipment contexts.

Selection Notes

Select this component when a robust, internally driven piezoelectric indicator is required for industrial or medical settings. The flange mount simplifies assembly compared to bracket-mounted alternatives. Consider the 90dB output sufficient for general area alerts but verify audibility in high-noise environments. The internal driver eliminates the need for external oscillating circuits, reducing board space and complexity.

Part Context

This part belongs to the SBT series of industrial buzzers from Mallory Sonalert. The SBT line is characterized by durable construction and standardized form factors for easy integration into control panels. The GLFL suffix typically denotes specific acoustic characteristics and mounting configurations within this product family, distinguishing it from other variants like SBT12CMFL or SBT12PMFL.

Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Evaluate SBT12GHFL for general industrial use or SBT12CMFL for cardiac-specific applications if acoustic profiles differ. Verify mechanical fit and electrical compatibility before substituting.
