MSE28MDT8S

Alarms, Buzzers, And Sirens Overview

The MSE28MDT8S is a piezoelectric buzzer from the Mallory Sonalert MSE series, designed for through-hole mounting. It features an internally driven circuit and operates on DC input within a voltage range of 20 to 28V. The device draws 50mA of supply current and produces a sound pressure level of 75dB at 20V measured at 30cm. It generates a continuous tone at a frequency of 3.85kHz. The unit measures 23.00mm x 23.00mm with a maximum installation height of 13.60mm and utilizes PC pins for termination.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric technology for direct connection
• Through-hole PC pin termination for board mounting
• Continuous tone output capability

Alarms, Buzzers, And Sirens Applications

• Industrial control panel indicators
• Equipment status alarms
• General purpose audio signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm electrical characteristics such as voltage rating and acoustic output. Ensure the PCB footprint matches the 23x23mm package dimensions and PC pin spacing. Confirm RoHS compliance requirements if applicable to your assembly process.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, internally driven piezo buzzer is required for through-hole applications. It is suitable for designs operating between 20V and 28V DC where a 3.85kHz continuous tone is appropriate. Consider the 75dB SPL rating relative to the ambient noise environment of the target application.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the MSE series of miniature board mount buzzers manufactured by Mallory Sonalert Products Inc. The series is characterized by small form factors and integrated drive circuits, allowing for simplified schematic design compared to passive transducers.

Alarms, Buzzers, And Sirens Replacement Considerations

MSE28LCH2 is a documented alternative in the same series offering similar dimensions and through-hole mounting but with different acoustic parameters.
