MSE28MCH2

Alarms, Buzzers, And Sirens Overview

The MSE28MCH2 is a miniature board mount piezoelectric buzzer from the MSE series by Mallory Sonalert. It operates on a DC voltage range of 16 to 28 V with a rated current of 50 mA. The device features an internally driven chirp tone at a frequency of 3.85 kHz, repeating every 1.2 seconds. It delivers a sound pressure level of 75 dBA at 16 V and up to 85 dBA at higher voltages within its operating range. Measuring 23 mm x 23 mm x 13.5 mm, it utilizes solder pin termination for PCB installation.
