SC250FK

Alarms, Buzzers, And Sirens Overview

The SC250FK is an industrial-grade piezoelectric buzzer from the Mallory Sonalert SC series. It operates on AC or DC voltages ranging from 60V to 250V with a current draw of 16mA. The device emits a soft, short pulse tone at a frequency of 2900Hz. Designed for flush mounting, it features screw terminals and quick connect tabs (0.250 inch). The unit has a diameter of 42.85mm and weighs approximately 45g.

Alarms, Buzzers, And Sirens Feature Summary

• Generates a soft, short-pulse audible alert suitable for industrial environments
• Operates on wide voltage ranges including both AC and DC inputs
• Features internal drive circuitry requiring no external components
• Supports secure panel mounting via flush installation style

Alarms, Buzzers, And Sirens Applications

• Industrial machinery status indication
• Factory equipment alarm systems
• Control panel audio signaling
• Heavy-duty process monitoring alerts

Alarms, Buzzers, And Sirens Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance in some regions. Confirm terminal type compatibility with existing wiring harnesses. Check regional availability restrictions as distribution may be limited. Ensure mounting hole dimensions match the 42.85mm diameter specification before integration into enclosure designs.

Alarms, Buzzers, And Sirens Selection Notes

Select this model for applications requiring a soft acoustic profile rather than high-decibel alarms. Suitable for environments where continuous loud noise is undesirable. Compare with SC250FJ for different pulse rates or SC250HR for constant tone requirements. Ensure operating voltage falls within the 60-250V range to prevent damage.

Alarms, Buzzers, And Sirens Part Context

Part of the Mallory Sonalert SC series, known for robust industrial audio indicators. The brand has over a century of history in electronic sound solutions. This specific model utilizes piezoelectric technology for reliable performance across varying temperatures and conditions typical in manufacturing settings.

Alarms, Buzzers, And Sirens Replacement Considerations

SC250FJR offers similar specifications with RoHS compliance and potentially different packaging. SC250FP provides a fast pulse variant at the same frequency. Verify electrical parameters and mounting styles when substituting to ensure mechanical and functional compatibility.
