SC628FJW

Overview

The SC628FJW is a piezoelectric audio indicator from the Mallory Sonalert SC series, designed for industrial applications. It operates on a DC voltage rating of 6 to 28 VDC with a typical current draw of 10 mA. The device produces a continuous tone at a frequency of 2.9 kHz and achieves a sound pressure level of 85 dBA. It features screw terminals for connection and is intended for panel mount installation. The unit has a diameter of 43 mm and a height of approximately 33 mm, weighing about 45 grams.

Feature Summary

• Piezoelectric technology ensures reliable operation across a wide voltage range without requiring external drivers.
• Continuous tone output provides consistent auditory signaling for status indication or alarm purposes.
• Screw terminal connections facilitate secure wiring in industrial control panels.
• Compact cylindrical form factor allows for straightforward integration into existing equipment enclosures.

Applications

• Industrial machinery status monitoring
• Control panel alarm systems
• Medical equipment auditory alerts
• Transportation vehicle instrumentation

Procurement Notes

Verify the specific suffix configuration against official Mallory Sonalert documentation to ensure correct voltage, tone type, and termination style. Confirm that the required sound pressure level and mounting dimensions align with the target enclosure specifications before finalizing procurement orders.

Selection Notes

Select this component when a moderate volume continuous alert is required within standard industrial voltage limits. Ensure the application environment falls within the specified operating temperature range and that panel cutout dimensions accommodate the 43 mm diameter housing for proper flush or panel mounting.

Part Context

This part belongs to the legacy SC628 series, which established the standard for electronic sounders since the 1960s. The SC series remains a foundational product line for Mallory Sonalert, widely recognized for its durability and consistent performance in critical signaling roles across various global industries.

Replacement Considerations

Consult official Mallory Sonalert cross-reference guides for direct replacements. Verify that any substitute maintains identical electrical ratings, acoustic output characteristics, and physical mounting constraints to ensure seamless integration without redesigning the host system.
