SC250EJR

Overview

The SC250EJR 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 rated current of 16 mA. The device produces a sound pressure level of 62-83 dB and features a single-pole (SP) configuration. Physical dimensions are 1.69 inches in length, 22 mm in width, and 1.9 inches in height, weighing 45 grams.

Feature Summary

• Industrial-grade construction designed for demanding environments
• Piezoelectric technology for reliable audio indication
• Internal driver circuitry for simplified integration

Applications

• Industrial machinery status indication
• Electrical panel alarm systems
• Heavy equipment operational alerts

Procurement Notes

Verify specific acoustic output requirements against the 62-83 dB range before procurement. Confirm voltage compatibility within the 60-250 VAC/DC specification. Check RoHS documentation status as indicated in official datasheets. Ensure mounting hardware matches the specified physical dimensions for proper installation.

Selection Notes

Select this model when high-voltage AC or DC operation is required without external drivers. The SC series offers robust performance for industrial settings. Consider the specific decibel range needed for the application environment. Verify terminal type compatibility during system design.

Part Context

This component belongs to the Mallory Sonalert SC series of industrial alarms. The series provides various piezoelectric indicators for different voltage and frequency requirements. The SC250EJR specifically targets higher voltage applications compared to lower voltage counterparts in the same family.

Replacement Considerations

Consult official Mallory Sonalert documentation for verified substitute part numbers. Cross-reference electrical specifications and physical dimensions carefully. No direct substitutes are confirmed in public data.
