SC628CPNR

Overview

The SC628CPNR 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 VDC and produces a continuous tone at a frequency of 2900 Hz. The device features screw terminals for connection and has a diameter of 43 mm (1.687 in). It is CUL approved and rated for industrial applications.

Feature Summary

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

Applications

• Industrial equipment status indication
• Control panel alarm systems
• Automotive diagnostic alerts

Procurement Notes

Verify the specific suffix 'R' against official Mallory documentation to confirm if it denotes a specific packaging variant or environmental rating distinct from the base SC628CPN model. Ensure the required voltage rating matches the 6-28 VDC specification before integration into the target circuit design.

Selection Notes

Select this component when a high-frequency continuous tone is required for audible warnings. The 2900 Hz frequency provides distinct audibility compared to lower-pitched alarms. Verify that the panel cutout dimensions accommodate the 43 mm diameter and that the enclosure supports the specified operating temperature range.

Part Context

This part belongs to the Mallory Sonalert SC series, a long-standing line of industrial audio indicators introduced in the 1960s. The series is known for robust construction and consistent performance in demanding environments, serving as a foundational component for various electronic warning systems across multiple industries.

Replacement Considerations

Direct substitutes within the same series include SC628CPN for identical electrical characteristics without the 'R' suffix designation. Cross-series replacements require matching the 2900 Hz frequency and 6-28 VDC operating range.
