SC628AFJR

Overview

The SC628AFJR is a piezoelectric audio indicator from the Mallory Sonalert SC series, designed for industrial applications. It operates on a voltage range of 6 to 28 VAC or VDC with a rated current of 8 mA. The device emits a soft slow pulse tone at a frequency of 2900 Hz and produces a sound pressure level of 74 dBA. It features screw terminals for connection and is constructed for panel mounting. The unit measures 43 mm in diameter and 35.54 mm in height, weighing approximately 45 g.

Feature Summary

• Generates a soft slow pulse acoustic signal suitable for non-intrusive alerting environments
• Utilizes piezoelectric technology for reliable operation across specified voltage ranges
• Designed for secure panel mounting using screw terminal connections

Applications

• Industrial equipment status indication
• Medical device audio signaling
• Transportation system alerts

Procurement Notes

Verify the specific suffix configuration against official Mallory Sonalert documentation to ensure correct tone and termination type. Confirm that the required voltage and current ratings align with the target circuit design. Check for any RoHS compliance variations or regional certification requirements such as CUL approval before finalizing procurement specifications.

Selection Notes

Select this model when a low-volume, soft-level slow pulse alarm is required for panel-mounted installations. Ensure the application environment supports the specified 6-28 V operating range. Compare against other SC series variants if higher sound pressure levels or different pulse rates are necessary for the specific safety or notification requirements.

Part Context

This component belongs to the Mallory Sonalert SC series, which has served as a foundational product line since the 1960s.
