SCH648AR

Alarms, Buzzers, And Sirens Overview

The SCH648AR is a piezoelectric buzzer from the SC series by Mallory Sonalert Products Inc., designed for panel mounting. It operates on an AC or DC input voltage range of 10 to 48V and produces a continuous tone at a frequency of 2900 Hz ± 500 Hz. The device features a medium sound level category with internal drive circuitry, requiring no external oscillators. It utilizes screw terminals for connection and is rated for operation within a temperature range of -30°C to 65°C.
