MSE28LSN3S

Alarms, Buzzers, And Sirens Overview

The MSE28LSN3S is a piezoelectric buzzer from the MSE series by Mallory Sonalert Products Inc. It features an internally driven indicator 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 85dB at 20V, measured at 30cm. It emits a tone frequency of 4kHz with a pulse rate of 7 pulses per second. The unit utilizes through-hole PC pin termination for board mounting and has dimensions of 23.00mm x 23.00mm.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific part number MSE28LSN3S against official Mallory Sonalert documentation to confirm the 4kHz frequency and 7 SPS pulse rate. Ensure the selected variant matches the required 20-28V operating range and through-hole mounting configuration for your PCB layout. Cross-reference datasheets for environmental ratings and certification compliance before finalizing procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact, internally driven buzzer is required for direct DC operation without external oscillators. The MSE series offers a balance of size and acoustic output suitable for panel-mounted applications. Consider the 50mA current draw and 85dB SPL for audibility requirements in noisy environments. Verify that the 23x23mm form factor fits the designated enclosure space.

Alarms, Buzzers, And Sirens Part Context

This component belongs to the MSE series of miniature board mount buzzers manufactured by Mallory Sonalert Products Inc. The series is designed for general-purpose audio indication in various electronic systems. These devices are known for their reliability and consistent performance across a wide temperature range, serving as standard indicators in industrial and commercial equipment.

Alarms, Buzzers, And Sirens Replacement Considerations

The MSE28LDP3S is a similar model within the same series but operates at a different frequency (3.9kHz) and pulse rate (0.5 PPS). Verify if the specific acoustic pattern and frequency differences impact the application's alarm recognition requirements before substituting.
