MSR414NSR

Alarms, Buzzers, And Sirens Overview

The MSR414NSR is a DC single-tone piezoelectric audio indicator manufactured by Mallory Sonalert Products Inc. It operates within a voltage range of 4V to 14V and draws an operating supply current between 3mA and 12mA. The device produces a sound pressure level of 88dB at 4V measured from a distance of 30cm, with a fundamental frequency of 3.5kHz. Designed for through-hole mounting via PC pins, it features a top port location and supports washable construction. The component functions in continuous mode and is classified as an internally driven piezo buzzer suitable for panel or board integration.
