Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm the exact acoustic profile and electrical characteristics. Ensure the procurement channel provides valid RoHS compliance documentation. Confirm that the solder pin configuration matches the target printed circuit board layout requirements before finalizing acquisition.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a compact board-mount solution is required for audible alerts within a 16 to 28 VDC system. The internal drive capability simplifies design by eliminating the need for external oscillators. Consider the 75-85 dBA output level relative to ambient noise conditions and the 23 mm footprint constraints of the enclosure.

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 suitable for space-constrained electronics.
