SC250PR

Overview

The SC250PR is an industrial-grade piezoelectric buzzer from the SC series, designed for panel mounting. It operates on AC or DC voltages ranging from 60 to 250 V with a rated voltage of 250 V and a current draw of 13 mA. The device emits a fast pulse tone at a frequency of 2.9 kHz. It features internal driver circuitry and utilizes screw terminals for connection. The unit measures 43 mm in diameter and 35.54 mm in height, weighing 45 g.

Feature Summary

• Internal driver circuitry enables direct connection to AC or DC power sources without external components.
• Piezoelectric technology generates a fast pulse acoustic signal for clear auditory indication.
• Industrial construction supports operation within a temperature range of -30°C to 65°C.

Applications

• Industrial machinery fault signaling
• Process control panel status indication
• Safety system alarm activation

Procurement Notes

Verify the specific suffix against official Mallory Sonalert documentation to confirm electrical characteristics and terminal type. Confirm RoHS compliance status through the manufacturer's latest certification documents. Ensure the operating environment falls within the specified temperature limits before deployment.

Selection Notes

Select this model when a high-voltage (up to 250 V) audible indicator is required. The internal driver simplifies integration by eliminating the need for separate drive electronics. Verify that the required sound pressure level meets application needs, as specifications vary across the SC series based on pulse rate and frequency.

Part Context

This component belongs to the SC series of industrial alarms manufactured by Mallory Sonalert Products Inc. The series is characterized by robust piezoelectric designs intended for harsh environments. These devices are widely used in sectors requiring reliable visual and auditory alerts for operational monitoring.

Replacement Considerations

SC250KR provides similar form factor and voltage ratings but differs in pulse duration characteristics. SC250JR offers a slow pulse variant within the same series. Verify dimensional compatibility and terminal configuration before substituting.
