SC250HJR

Overview

The SC250HJR is a piezoelectric buzzer from the Mallory Sonalert SC series, designed for industrial audio indication. It operates on AC or DC input within a voltage range of 60 to 250V and draws a supply current of approximately 16 mA. The device generates a medium-pitched pulse tone at a frequency of 4500 Hz with a sound pressure level of 80 dBA. Featuring internal drive circuitry, it utilizes screw terminals for connection and is constructed for panel mounting.

Feature Summary

Internal drive circuitry enables direct connection to high-voltage AC or DC sources without external drivers.
Piezoelectric technology ensures reliable operation in demanding industrial environments.
Screw terminal connections provide secure electrical attachment for panel-mounted installations.

Applications

Industrial machinery status indicators
High-voltage control panel alarms
Factory automation system alerts

Procurement Notes

Verify the specific suffix against official Mallory Sonalert documentation to confirm the exact acoustic output characteristics, as variations exist within the SC series. Confirm that the required operating voltage aligns with the 60-250V specification before integration into the target circuit design.

Selection Notes

Select this component when a high-frequency (4500 Hz) audible alert is required for systems powered by voltages up to 250V. Ensure the application supports the specified 80 dBA sound pressure level and that the physical dimensions accommodate the designated panel space.

Part Context

This part belongs to the SC series of industrial buzzers manufactured by Mallory Sonalert Products Inc. The series is characterized by robust construction suitable for harsh environments, utilizing piezoelectric elements for consistent performance across a wide temperature range.

Replacement Considerations

SC250DJR: Offers similar form factor but differs in acoustic profile (66-75dB). SC250FPR: Alternative variant with different sound characteristics (62-70dB). Verify functional equivalence via official datasheets before substitution.
