SBT12DMPC

Overview

The SBT12DMPC is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc., designed for through-hole mounting. It features an internal driver circuit and accepts DC input. The device operates within a voltage range of 9 to 12 VDC, with a rated voltage of 12 VDC. It produces a sound pressure level of 90 dB at 10 cm. The unit has a diameter of 44.45 mm and is certified under IEC standards.

Feature Summary

• Piezoelectric technology with integrated internal driver circuitry
• Through-hole mounting configuration with top port location
• IEC standard certification for industrial applications
• Single-tone operation mode

Applications

• Industrial audio indicators
• Sound alert systems
• Medical equipment alarms
• Transportation signaling devices

Procurement Notes

Verify the specific suffix 'M' against official datasheets to confirm mechanical dimensions and terminal type. Ensure the operating voltage matches the 9-12 VDC requirement. Confirm RoHS compliance status via current manufacturer documentation before integration into regulated assemblies.

Selection Notes

Select this component when a high-decibel, internally driven piezoelectric buzzer is required for panel or chassis mounting. The 44.45 mm diameter suits standard industrial enclosures. Verify that the 90 dB output meets acoustic requirements without excessive power consumption compared to magnetic alternatives.

Part Context

This part belongs to the SBT series of industrial-grade buzzers from Mallory Sonalert. The series includes variants with different acoustic profiles such as cardiac, general, and temperature-energy tones. The SBT12DMPC specifically denotes the 12VDC piezoelectric model with through-hole terminals.

Replacement Considerations

Direct substitutes include other SBT series models like SBT12GHFL or SBT12TMFL if acoustic tone differences are acceptable. Verify pinout compatibility and mounting hole alignment when cross-referencing with generic piezoelectric buzzers.
