Overview

The MSS5MMT is an internally driven magnetic buzzer designed for medical applications requiring high reliability and specific signaling patterns. It operates from a 5V DC source and features pin-selectable operating modes, allowing engineers to choose between different acoustic durations and sound patterns at a resonant frequency of 2.075kHz.

Why Choose This Part

This indicator is rated for medical use and includes internal circuitry to simplify design, eliminating the need for an external oscillator. The pin-selectable logic allows for multiple signaling behaviors within a single hardware footprint, while the 85dB output ensures clear audibility at a 10cm distance.

Applications

Medical Monitoring Equipment
Used in patient monitors and diagnostic devices to provide audible alerts for critical status changes.
Infusion Pumps
Provides safety-critical alarms for occlusion or end-of-dosage notifications in clinical environments.
Laboratory Instrumentation
Integrates into analyzers to signal task completion or error states in a controlled environment.

Getting Started

Integration requires a 4.5V to 5.5V DC supply and basic GPIO control to select the desired operating mode via the dedicated pins. Ensure the 2.5mm pitch PC pins are correctly oriented for the top-port sound output and provide sufficient current (up to 150mA) for peak operation.
