- Internally driven piezoelectric technology for direct connection
- IEC60601-1-8 AMD1 certification for medical drug or fluid delivery melodies
- PCB mount design with solder termination for secure integration
Applications
- Medical device alarms
- Drug delivery system indicators
- Fluid delivery monitoring alerts
Procurement Notes
Verify the specific suffix 'MPPC' against the official Mallory Sonalert datasheet to confirm the exact melody configuration and terminal type. Ensure the procurement channel provides valid RoHS documentation and IEC60601-1-8 AMD1 compliance certificates. Confirm that the operating voltage range matches the system requirements before finalizing the order.
Selection Notes
Select this component when a certified medical-grade audible alert is required for drug or fluid delivery systems. The internal drive circuit simplifies board layout by eliminating external driver components. Verify that the 100dB output level meets the acoustic requirements of the intended enclosure and environment.
Part Context
This part belongs to the Mallory Sonalert audio indicators and alerts portfolio, specifically designed for industrial and medical applications. The manufacturer specializes in piezoelectric buzzers and speakers for critical signaling needs. This model represents a specialized variant tailored for regulated medical environments requiring specific melody outputs.
Replacement Considerations
Consult the official Mallory Sonalert cross-reference guide for verified substitutes. Generic piezo buzzers may lack the required IEC60601-1-8 AMD1 certification or specific melody programming necessary for compliant replacement.
