SC628AF

Overview

The SC628AF is a piezoelectric audio indicator from the Mallory Sonalert SC series. It operates on a voltage range of 6 to 28 VAC or DC with a rated current of 15 mA. The device produces a continuous tone at a frequency of 2 kHz and achieves a sound pressure level of 95 dBA. It features screw terminals for connection and is designed for panel mounting. The unit has a diameter of 43 mm and a height of 48.51 mm, weighing approximately 60 g.

Feature Summary

Piezoelectric technology for reliable acoustic signaling
Continuous tone operation for persistent alerts
Screw terminal termination for secure electrical connections
Panel mount installation style

Applications

Industrial machinery status indication
Control panel alarm systems
Automotive equipment monitoring
HVAC system fault detection

Procurement Notes

Verify the specific suffix code (e.g., ND, MH) as the base model SC628AF may represent a generic family designation. Confirm exact voltage ratings, sound pressure levels, and termination styles against the official datasheet before procurement. Ensure compatibility with existing panel cutouts and wiring configurations.

Selection Notes

Select based on required sound pressure level and operating frequency. Verify voltage compatibility with the control circuit. Consider mounting style and terminal type for integration. Check environmental ratings if used in harsh conditions. Compare variants within the SC series for specific acoustic or electrical requirements.

Part Context

The SC628AF belongs to the Mallory Sonalert SC series of industrial audio indicators. This series is known for robust construction and consistent performance in demanding environments. The components are widely used in applications requiring clear and audible alerts for operational status or fault conditions.
