Mallory Sonalert has expanded its portfolio of audio indicators and speakers, including surface-mount technology (SMT) speakers and audible/visual alarms. The audio indicators feature embedded LEDs and a wide DC voltage range. The audio indicators are available in a variety of package types, including board-level, panel-level, and bracket-mount configurations. The SMT speakers are highly durable against solder reflow operation, which does not affect the speakers’ functionality. The speakers provide an 8Ω voice coil impedance rating and operate within an 850Hz to 20KHz broad frequency range.
