SC628MAH

Overview

The SC628MAH is an internally driven piezoelectric buzzer from the Mallory Sonalert SC series, designed for audible alerts and status indication. It operates on a voltage range of 6 to 28 VAC or VDC with a current draw of 4 to 16 mA. The device produces a continuous tone at a frequency of 4.5 kHz. It features screw terminals and quick-connect tabs (0.250 inch) for panel mounting. The unit has a diameter of approximately 43 mm and a height of 35.54 mm.

Feature Summary

• Internally driven piezoelectric technology for direct connection to power sources
• Industrial-grade construction suitable for control panels and equipment
• Versatile terminal options including screw connections and quick-connect tabs

Applications

• Equipment status indication in industrial control panels
• Audible warning signals for machinery and systems
• General purpose alarm applications requiring reliable audio alerts

Procurement Notes

Verify the specific suffix MAH against official Mallory Sonalert documentation to confirm terminal type and environmental ratings. Ensure the required operating voltage aligns with the 6-28V AC/DC specification. Confirm that the panel cutout dimensions match the 43 mm diameter requirement for proper installation.

Selection Notes

Select this model when a continuous 4.5 kHz alert is required without external driving circuitry. The internal drive simplifies integration into existing DC or AC systems. Consider the physical dimensions and mounting style to ensure compatibility with the target enclosure design and available space constraints.

Part Context

The SC628MAH belongs to the SC series of industrial alarms manufactured by Mallory Sonalert Products Inc. This series is known for robust performance in demanding environments. The component serves as a fundamental audio signaling device, replacing older mechanical buzzers with more reliable solid-state piezoelectric alternatives.

Replacement Considerations

SC628AH is a confirmed substitute part number within the same product family.
