SC250FR

Overview

The Mallory Sonalert SC250FR is an industrial-grade constant piezo buzzer designed for high-voltage applications. It operates within a voltage range of 60 to 250 V and produces a sound frequency of 2900 Hz with a soft tone characteristic. The unit draws a current of 4 mA and features flush mount installation. Its physical dimensions are 1.69 inches in length, 1.69 inches in width, and 1.41 inches in height, weighing 45 grams. This component belongs to the SC series and is classified under audio indicators and alerts.

Feature Summary

• Industrial-grade construction suitable for demanding environments
• Constant output capability across a wide voltage range
• Soft acoustic profile for reduced noise intensity

Applications

• High-voltage industrial machinery status indication
• Electrical panel alarm systems
• Heavy equipment operational alerts

Procurement Notes

Verify the specific suffix requirements against the official Mallory Sonalert datasheet to ensure compatibility with your system's mounting and electrical constraints. Confirm that the 250 V rating aligns with your circuit design. Check for RoHS compliance details if required by your manufacturing standards. Ensure the flush mount style matches your enclosure specifications before finalizing the order.

Selection Notes

Select this model when a constant tone indicator is required for circuits operating between 60 and 250 V. The 4 mA current draw makes it suitable for low-power control signals. Consider the 2900 Hz frequency for audibility in noisy industrial settings. The flush mount design is ideal for panels requiring a low-profile installation. Verify that the soft tone meets the specific acoustic requirements of the application environment.

Part Context

The SC250FR is part of the SC series from Mallory Sonalert, which specializes in audio indicators. This series is engineered for reliability in industrial sectors. The component serves as a visual and auditory alert mechanism. It is distinct from lower-voltage consumer variants due to its robust construction and higher voltage tolerance. The SC series is widely recognized for consistent performance in critical signaling roles.

Replacement Considerations

Consult the official Mallory Sonalert cross-reference guide for verified substitutes. Ensure any replacement matches the 60-250 V operating range and 2900 Hz frequency. Verify that the new part supports flush mounting and similar physical dimensions. Do not assume interchangeability based on voltage alone; acoustic characteristics must also align.
