SBT12PMPC

Overview

The SBT12PMPC is an industrial-grade magnetic buzzer from the Mallory Sonalert SBT series, designed for perfusion and medical applications. It operates on a DC input voltage range of 9 to 12VDC with a rated voltage of 12V. The device produces a sound pressure level of 90dB at 10cm. It features internal drive circuitry for direct connection to power sources. The unit utilizes PC pin terminals for through-hole mounting and is certified by cUL and UL standards.

Feature Summary

• Industrial-grade construction suitable for demanding environments
• Internal drive circuitry allows direct DC connection without external oscillators
• Certified for medical and safety applications under cUL and UL standards
• Designed specifically for perfusion pump audio indication

Applications

• Perfusion pump audio indicators
• Medical equipment alarm systems
• Industrial panel alarms requiring high reliability
• Safety warning devices in controlled environments

Procurement Notes

Verify that the specific application requires the 9-12VDC operating range and 90dB output level. Confirm that through-hole PC pin termination matches the PCB layout. Ensure the design complies with relevant cUL and UL certification requirements for the intended end-use environment. Check for any specific medical compliance documentation if used in regulated healthcare settings.

Selection Notes

Select this component when a robust, internally driven buzzer is needed for 9-12VDC systems. The SBT series offers higher durability compared to standard consumer buzzers. Consider the 90dB acoustic output for noise-intensive areas. The medical-grade designation supports use in sensitive instrumentation where consistent performance is critical.

Part Context

This part belongs to the SBT (Sonalert Buzzer Type) series, which represents Mallory's industrial and medical line of audio indicators. Unlike the MSS or MSE series, the SBT series focuses on ruggedized performance and specialized certifications. It shares the internal drive architecture but differs in voltage ratings and acoustic profiles tailored for professional and clinical installations.

Replacement Considerations

Direct replacements must match the 9-12VDC input, 90dB SPL, and through-hole PC pin configuration. Verify physical dimensions and mounting hole patterns. Ensure substitute parts maintain cUL/UL recognition if required by the original equipment specification.
