SC110HPR

Overview

The SC110HPR is an industrial-grade piezoelectric buzzer from the Mallory Sonalert SC series, designed for high-voltage applications. It operates on a rated voltage of 120 VAC or 120 VDC with a current draw of 20 mA. The device produces a medium-intensity fast pulse tone at a frequency of 4.5 kHz, achieving a sound pressure level of 80 dBA. It features screw terminals for connection and supports panel mount installation. The unit measures 43 mm in diameter and 1.41 inches in height, weighing 45 grams.

Feature Summary

• Piezoelectric construction for reliable audio signaling
• Integrated operation at 120 VAC/DC without external drivers
• Fast pulse tone generation for distinct alert identification
• Screw terminal connections for secure electrical interface

Applications

• Industrial machinery status indication
• High-voltage control panel alarm systems
• Factory automation equipment alerts
• Electrical cabinet safety warnings

Procurement Notes

Verify the specific suffix HPR against the official Mallory Sonalert datasheet to confirm the fast pulse characteristic and voltage rating. Ensure the mounting hole diameter matches the 43 mm specification. Confirm that the screw terminal type aligns with the available wiring infrastructure. Check for any recent Product Change Notices (PCN) that may affect physical dimensions or material composition before finalizing procurement.

Selection Notes

Select this component when a direct 120 VAC/DC drive is required without additional circuitry. The 4.5 kHz frequency provides clear audibility in noisy environments. Compare the 80 dBA output against ambient noise levels to ensure adequate warning. Consider the panel mount style and screw termination requirements during mechanical design integration. Verify compatibility with existing enclosure cutouts and wiring methods.

Part Context
