SC250FP

Overview

The Mallory Sonalert SC250FP is an industrial-grade piezoelectric buzzer designed for high-voltage applications. It operates within a voltage range of 60 to 250 VAC/DC and draws a current of 14 mA. The device emits a fast pulse tone at a frequency of 2900 Hz with a sound pressure level between 62 and 70 dB. Its physical dimensions are 1.69 inches in length, 1.69 inches in width, and 1.41 inches in height, weighing approximately 45 grams. This component belongs to the SC series of audio indicators.

Feature Summary

• Capable of operating on both AC and DC power supplies within a wide voltage range.
• Generates a distinct fast-pulse acoustic signal suitable for industrial alerts.
• Constructed as a robust unit intended for demanding industrial environments.

Applications

• Industrial machinery status indication
• High-voltage equipment alarm systems
• General industrial audio signaling

Procurement Notes

Verify the specific suffix requirements when ordering, as variants such as SC250FPR may exist with different packaging or compliance markings. Confirm that the 60-250V operational range matches the target circuit design. Check for RoHS compliance documentation if environmental regulations apply to the deployment location. Ensure the fast-pulse characteristic meets the auditory notification standards required by the system specification.

Selection Notes

Select this model when a high-voltage input is available directly without additional driver circuitry. The 2900 Hz frequency provides a sharp alert tone. Consider the physical size constraints against the 1.69 x 1.69 inch footprint. Compare sound output levels against ambient noise requirements in the installation area. Verify compatibility with existing mounting hardware due to the specific housing dimensions.

Part Context

This component is part of the Mallory Sonalert SC series, which focuses on industrial audio indicators. The series includes various models tailored for different voltage and acoustic requirements. The SC250FP specifically addresses high-voltage direct drive needs, distinguishing it from lower-voltage counterparts in the same product family.

Replacement Considerations

The SC250FPR is a related variant within the same series. Verify if the 'R' suffix indicates a specific packaging difference or regulatory update rather than a functional change. No other direct cross-model substitutes are confirmed in the provided data.
