Procurement Notes

Verify the specific suffix configuration against the official Mallory Sonalert datasheet to ensure compatibility with required voltage and acoustic parameters. Confirm that the screw terminal type matches the assembly interface. Check for any recent product change notices or environmental compliance updates prior to finalizing procurement orders.

Selection Notes

Select this component when a loud, continuous audible alert is required for industrial applications. The wide voltage input range simplifies integration into various power supply architectures. Ensure the panel cutout accommodates the 43 mm diameter and verify that the mounting depth fits within the enclosure constraints.

Part Context

This model belongs to the SC series of panel-mount buzzers from Mallory Sonalert. The series is established for providing reliable audio signaling in demanding environments. The SC628FKR variant specifically addresses needs for high-volume sound output with durable mechanical connections.

Replacement Considerations

Direct substitutes must match the 43 mm diameter, screw terminal style, and 6-28 VDC operating range. Verify equivalent sound pressure levels and frequency specifications to maintain alarm audibility standards.
