Overview
The Mallory Sonalert SC250HR is an industrial-grade piezoelectric buzzer designed for high-voltage applications. It operates on a continuous tone at a frequency of 4.5 kHz with a sound pressure level of 80 dBA. The device supports voltage ratings of 60 to 250 VAC or 250 VDC and draws a current of 16 mA. It features screw terminals for connection and panel mount installation. Physical dimensions are 43 mm in diameter and 33 mm in width, with a height of 1.41 inches. The unit weighs 45 grams and belongs to the SC series.
Feature Summary
- Industrial-grade construction suitable for demanding environments
- Piezoelectric technology for reliable acoustic output
- High-voltage compatibility for direct AC/DC integration
Applications
- Industrial machinery status indication
- High-voltage control panel alarms
- Factory automation safety alerts
Procurement Notes
Verify the specific suffix HR against official Mallory Sonalert documentation to confirm compliance requirements such as CUL certification. Ensure the operating voltage range aligns with the system's available power supply. Confirm that the screw terminal type matches existing wiring infrastructure. Check RoHS status details in the latest datasheet before finalizing procurement specifications.
Selection Notes
Select this component when high-voltage operation up to 250 VAC/DC is required without external drivers. The 80 dBA output provides clear audible signaling in noisy industrial settings. Consider the physical size constraints for panel mounting. Compare with lower voltage variants like the SC628H if system voltage is below 60 VAC.
Part Context
The SC250HR is part of the Mallory Sonalert SC series of audio indicators. This series focuses on robust, piezoelectric buzzers for industrial use. The model specifically addresses high-voltage needs, distinguishing it from low-voltage counterparts in the same product family. It serves as a direct interface for alarm systems requiring significant drive voltage.
