SBT12MMTPC

Overview

The SBT12MMTPC is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It features through-hole mounting and operates within a voltage range of 9 to 12 VDC. The device produces a continuous tone at a frequency of 2.9 kHz with a sound pressure level of 90 dBA. It has a maximum current draw of 18 mA and utilizes solder lug termination for electrical connection. The unit is designed for industrial applications and complies with RoHS standards.

Feature Summary

• Piezoelectric technology for reliable audio indication
• Through-hole installation for secure panel mounting
• Continuous tone output for steady state alerts
• Industrial grade construction for durability

Applications

• Industrial machinery status indicators
• Medical equipment alarm systems
• Control panel auditory feedback
• Safety warning devices in manufacturing environments

Procurement Notes

Verify the specific suffix 'TPC' against official Mallory Sonalert documentation to confirm terminal type and compliance certifications. Ensure the operating voltage matches the 9-12 VDC requirement. Confirm that solder lug termination is compatible with the target assembly process. Check for current RoHS compliance status before finalizing procurement specifications.

Selection Notes

Select this component when a continuous audible alert is required for industrial or medical panels. The through-hole design suits high-vibration environments where surface mount options may fail. Consider the 90 dBA output level for noise attenuation requirements. Verify space constraints for the 44.5 mm diameter form factor during mechanical integration.

Part Context

This part belongs to the SBT series of industrial alarms from Mallory Sonalert. The series is recognized for meeting IEC 60601-1-8 standards in medical contexts. The manufacturer emphasizes long-term reliability and consistent acoustic performance across their audio indicator lineup.

Replacement Considerations

Consult official Mallory Sonalert substitution guides for direct equivalents. Verify pinout compatibility if replacing with similar piezoelectric buzzers. Ensure acoustic output levels meet regulatory requirements for the new application context.
