SC628CPN

Overview

The SC628CPN is a piezoelectric audio indicator manufactured by Mallory Sonalert Products Inc. It operates on a DC voltage range of 6 to 28 VDC with a rated current of 16 mA. The device produces a continuous tone at a frequency of 2900 Hz and achieves a sound pressure level of 68 dBA. It features panel mounting with screw terminals and has a diameter of 43 mm (1.687 in). The unit carries CUL approval.

Feature Summary

• Piezoelectric technology for reliable acoustic signaling
• CUL approved for safety compliance
• Panel mount design with screw terminal connections

Applications

• Industrial equipment status indication
• Control panel alarm systems
• Automated machinery fault alerts

Procurement Notes

Verify the specific suffix CPN against official Mallory documentation to confirm terminal type and certification status. Ensure the application voltage remains within the 6-28 VDC range. Confirm that the 68 dBA output meets environmental noise requirements. Check for RoHS compliance details as indicated in manufacturer specifications.

Selection Notes

Select this model when a moderate volume alert is required for industrial panels. The 2900 Hz frequency provides distinct audibility. Compare with other SC series variants if higher decibel levels or different pulse modes are needed. Verify physical dimensions fit the enclosure cutout.

Part Context

Part of the SC series from Mallory Sonalert, established since the 1960s. This line focuses on robust industrial audio indicators using piezoelectric elements. The SC series is widely used in automation and control applications requiring durable, panel-mounted audible alarms.
