MSE14MDT8S

Alarms, Buzzers, And Sirens Overview

The MSE14MDT8S is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a voltage range of 7 to 14 VDC with an internal driver circuit. The device features a dual-tone sound mode operating at frequencies between 3.7 kHz and 3.8 kHz, producing 1.5 waves per second. It delivers a sound pressure level of 75 dB measured at 7V and 30cm distance. The component utilizes through-hole PC pin termination and has a physical size of 23mm x 23mm.

Alarms, Buzzers, And Sirens Feature Summary

• Internally driven piezoelectric technology for direct DC input
• Dual-tone acoustic output with variable frequency modulation
• Through-hole mounting configuration with PC pins
• High sound pressure level efficiency relative to power consumption

Alarms, Buzzers, And Sirens Applications

• Medical device alarm systems requiring IEC60601-1-8 compliance
• Industrial control panel indicators
• Equipment status signaling in transportation systems
• General purpose audible alerts in consumer electronics

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix 'DT8S' against the official Mallory Sonalert datasheet to confirm the dual-tone 1.5 WPS characteristic. Ensure the ordering part number matches the required through-hole package dimensions and PC pin spacing. Confirm RoHS3 compliance status if environmental regulations apply to the end product assembly process.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a distinct dual-tone alert is required without external driving circuitry. The 7-14VDC rating suits applications where higher voltage rails are available. Consider the 75dB SPL for environments requiring moderate audibility. Verify that the 23x23mm form factor fits within the designated enclosure space constraints.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the MSE series of medical-grade piezo buzzers from Mallory Sonalert. The series is designed for high reliability and washability. The MSE14MDT8S specifically addresses needs for complex tone patterns in critical signaling applications, differentiating it from single-tone or continuous wave variants within the same product family.

Alarms, Buzzers, And Sirens Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 75dB SPL, 7-14VDC range, and dual-tone 1.5WPS specification exactly.
