MSS5TH

Alarms, Buzzers, And Sirens Overview

The MSS5TH is a magnetic buzzer manufactured by Mallory Sonalert Products Inc., designed for through-hole mounting. It operates on a DC input with a rated voltage of 5V and a functional range of 4 to 6V. The device features internal drive circuitry, eliminating the need for external oscillators. Key electrical parameters include a supply current of 46 to 150mA and an operating frequency of 2.075kHz. It produces a sound pressure level of 85dB at 5V measured from a distance of 10cm. The unit measures 23x23mm and utilizes PC pins for termination.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix or variant against the official datasheet to ensure compliance with intended application requirements. Confirm that the through-hole package dimensions and pin spacing match the target PCB layout. Check for any specific regulatory certifications required for the end product, such as UL or cUL listings, which are documented for this series.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a self-oscillating magnetic buzzer is required for low-voltage DC systems. The internal driver simplifies the schematic compared to passive buzzers. Ensure the available board space accommodates the 23x23mm footprint and that the 46-150mA current draw is supported by the power supply design.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the MSS series of audio indicators from Mallory Sonalert. The series includes various acoustic outputs and mounting styles tailored for industrial and medical environments. The MSS5TH specifically addresses the need for reliable, high-decibel signaling in compact electronic assemblies requiring direct DC connection.

Alarms, Buzzers, And Sirens Replacement Considerations

Consult the manufacturer's cross-reference documentation for verified substitutes. Ensure any replacement maintains the same voltage rating, current consumption limits, and acoustic output specifications to preserve system functionality.
