SC250EPR

Overview

The SC250EPR is a piezoelectric buzzer from the Mallory Sonalert SC series, designed for panel mounting. It operates on AC or DC voltages ranging from 60V to 250V with a current draw of 5mA to 16mA. The device emits a fast pulse tone at a frequency of 1900Hz (approximately 2kHz). It features an internal driver and indicator light, housed in a 42.85mm diameter unit with screw terminals and quick-connect tabs.

Feature Summary

Piezoelectric technology with integrated internal driver and visual indicator
Fast pulse sound mode for distinct audio alerts
Compatible with wide voltage range of 60-250V AC/DC
Panel mount design with dual termination options

Applications

Industrial machinery status indication
Control panel alarm systems
Equipment fault signaling
Safety warning devices

Procurement Notes

Verify the specific suffix 'EPR' against official Mallory Sonalert documentation to confirm the fast pulse variant and terminal configuration. Ensure the operating environment falls within the specified voltage and temperature limits. Cross-reference the datasheet for exact acoustic output levels and mechanical dimensions prior to integration.

Selection Notes

Select this component when a high-volume industrial alert is required without external driving circuitry. The SC250EPR is suitable for applications needing immediate visual and auditory feedback. Compare with other SC series variants if different pulse rates or frequencies are needed. Confirm panel cutout requirements match the 42.85mm diameter specification.

Part Context

This part belongs to the Mallory Sonalert SC series of industrial alarms. These units are characterized by their robust construction and ability to operate directly from line voltages. The SC series typically includes various pulse rates and frequencies to suit different alerting needs across heavy industry and automation sectors.

Replacement Considerations

SC250KR offers a similar form factor but differs in pulse rate and frequency specifications. SC250JR provides a slow pulse option within the same voltage range. Verify electrical parameters and acoustic characteristics before substituting any alternative model.
