SC628ADP

Overview

The SC628ADP is a piezoelectric buzzer from the Mallory Sonalert SC series, designed for industrial audio indication. It operates on an AC/DC input voltage range of 6 to 28V and draws a supply current between 6 and 20mA. The device produces a fast pulse tone at a frequency of 2kHz with a sound pressure level of 60dB measured at 7.5V and 61cm. It features panel mount installation via screw terminals or quick-connect tabs (0.250 inch). The unit has a diameter of 42.85mm and a maximum height of 35.54mm, operating within a temperature range of -30°C to 65°C.

Feature Summary
