SC628APR

Overview

The SC628APR is a piezoelectric audio indicator from the Mallory Sonalert SC series, designed for panel mounting. It operates on a voltage range of 6 to 28 VAC or VDC with a current rating of 16 mA. The device produces a continuous tone at a frequency between 2400 Hz and 3400 Hz, generating a sound pressure level of 68 dBA. It features screw terminals for connection and has physical dimensions of approximately 43 mm in diameter by 36 mm in height.

Feature Summary

• Piezoelectric transducer technology for reliable acoustic output
• Continuous tone generation capability
• Screw terminal electrical connections
• Panel mount installation style

Applications

• Industrial equipment status indication
• Control panel alarm signaling
• Transportation vehicle monitoring systems
• Medical device alert indicators

Procurement Notes

Verify the specific operating frequency within the 2400-3400 Hz range required for your application, as this parameter can vary. Confirm that the 68 dBA sound pressure level meets the ambient noise requirements of the installation site. Ensure the panel cutout dimensions accommodate the 43 mm diameter housing. Check for any regional compliance certifications such as CUL if applicable to your market.

Selection Notes

Select this model when a moderate volume continuous audible warning is sufficient. The 68 dBA rating makes it suitable for environments where extremely loud alarms are not necessary. Compare against higher decibel variants like the SC628ANPR if louder alerts are needed. Consider the screw terminal interface for secure wiring in industrial settings compared to wire lead options.

Part Context

The SC628APR belongs to the long-standing SC series of Sonalert devices, which have been produced since the 1960s. This series is recognized as a standard for panel-mounted audio indicators across various sectors. The component represents a foundational design in Mallory Sonalert's portfolio, offering consistent performance for general-purpose alarm applications.

Replacement Considerations

Direct replacements may include other SC series models with similar voltage and mounting specifications but different acoustic characteristics. Verify compatibility with existing panel cutouts and wiring configurations before substituting.
