MSE28MDD7S

Alarms, Buzzers, And Sirens Overview

The MSE28MDD7S is a miniature board-mount piezoelectric buzzer from the Mallory Sonalert MSE series. It operates on a DC voltage range of 16 to 28V and draws 50mA. The device produces a 'Ding Dong' tone at a frequency of 3.5 kHz with a sound pressure level of 75-85 dBA. Physical dimensions are 23 mm x 23 mm x 14 mm, featuring solder pin termination for PCB mounting.

Alarms, Buzzers, And Sirens Feature Summary

• Sealed construction designed for environmental protection
• Integrated internal driver circuitry for direct operation
• Distinctive Ding Dong acoustic pattern generation

Alarms, Buzzers, And Sirens Applications

• Industrial control panel status indication
• Appliance operational alerts
• General purpose audible signaling systems

Alarms, Buzzers, And Sirens Procurement Notes

Verify specific lot codes and RoHS compliance documentation upon order confirmation. Confirm that the sealed variant matches the required environmental protection standards for the target application. Ensure input voltage stability within the 16-28V DC range to maintain specified acoustic performance and prevent component stress.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a compact, sealed buzzer with a unique two-tone alert is required. It is suitable for applications needing higher visibility than standard continuous tones but lower complexity than programmable alarms. Verify that the 23mm footprint fits the available PCB space and that the solder pin termination aligns with the assembly process.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the MSE series of miniature buzzers, which are characterized by their small form factor and integrated drivers. The series offers various acoustic patterns and voltage ratings to suit different board-mount requirements. The MSE28MDD7S specifically addresses needs for distinct, non-standard alert sounds in confined spaces.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes include other MSE series variants with similar voltage and current ratings, such as MSE28LTT3 or MSE28MCM3, provided the acoustic pattern difference is acceptable. Cross-series replacements require verification of mounting dimensions and electrical characteristics.
