SC628ANR

Overview

The SC628ANR is an industrial-grade piezoelectric buzzer from the Mallory Sonalert SC series, designed for panel mounting applications. It operates on a voltage range of 6 to 28 VAC or VDC with a rated current of 30 mA. The device produces a fast pulse tone at a frequency of 2.9 kHz and achieves a sound pressure level of 95 dBA. It features screw-type terminals for secure electrical connection and has physical dimensions of 43 mm in diameter by 1.41 inches in height.

Feature Summary

• Industrial-grade construction with CUL approval for safety compliance
• Piezoelectric technology delivering high-intensity audible alerts
• Fast pulse audio pattern for distinct warning signals
• Screw terminal interface ensuring robust mechanical and electrical stability

Applications

• Industrial machinery fault indication
• Control panel status monitoring
• Safety system alarm signaling

Procurement Notes

Verify that the specific suffix ANR corresponds to the Fast Pulse configuration and CUL approval as documented. Confirm that the required operating voltage falls within the 6-28 VAC/VDC range. Ensure the installation environment supports the specified panel mount style and screw terminal connections. Cross-reference the exact part number against official Mallory Sonalert catalogs to confirm availability and specifications.

Selection Notes

Select this component when a loud, distinct fast-pulse alert is required for industrial environments. The 95 dBA output ensures audibility in noisy settings. The wide voltage tolerance simplifies integration into various power systems. Verify that the 43 mm diameter fits the designated panel cutout and that screw terminals are preferred over wire leads for the specific assembly requirements.
