SBS12LMMXPC

Mallory Sonalert Products Inc.
Buzzers Indicator, Internally Driven Magnetic 40 ~ 200mA 2.075kHz 95dB @ 9V, 10cm Through Hole PC Pins
Active

Overview

The SBS12LMMXPC is a medical-grade internally driven magnetic buzzer designed for high-reliability signaling. Operating between 9V and 12V DC, it produces a 2.075kHz tone with a high output level of 95dB to 105dB at 10cm. This component features pin-selectable operating modes and a through-hole design for secure PCB mounting.

Why Choose This Part

This buzzer offers an integrated driver, simplifying circuit design by requiring only a DC voltage rather than an external oscillator. Its medical rating ensures performance consistency, and the pin-selectable modes provide flexibility in alarm sound patterns without software changes.

Applications

Medical Equipment Alarms
Used in patient monitors and diagnostic tools where high-reliability audible alerts are required.
Safety Systems
Integration into functional safety panels requiring high-volume signaling (95dB+).
Industrial Control Panels
Used as a status indicator or alarm in environments with high ambient noise levels.
