SC628EJR

Overview

The SC628EJR is an industrial-grade piezoelectric buzzer from the Mallory Sonalert SC series. It operates on a voltage range of 6 to 28 VDC and draws a current of 28 mA. The device produces a slow pulse tone at a frequency of 1900 Hz with a soft acoustic output level of 78 dBA. It features screw terminals for connection and is designed for flush mounting applications.

Feature Summary

• Generates a slow pulse audio signal for status indication
• Utilizes piezoelectric technology for reliable operation
• Designed for flush mounting in industrial enclosures

Applications

• Industrial equipment status monitoring
• Control panel alarm systems
• Process safety warning indicators

Procurement Notes

Verify that the specific suffix 'JR' corresponds to the required reel or packaging configuration if applicable, as standard datasheets may list the base model SC628EJ. Confirm the operating voltage matches the system supply exactly within the 6-28 VDC range. Ensure the enclosure allows for the specified flush mounting style and that the 78 dBA output meets the environmental noise requirements.

Selection Notes

Select this component when a low-volume, intermittent pulse alert is required for industrial panels. The SC628EJR offers a softer acoustic profile compared to continuous loud variants. Consider the 43 mm diameter for cutout compatibility. Verify that the screw terminal interface aligns with the wiring harness design.

Part Context

This part belongs to the Mallory Sonalert SC series, which provides industrial-grade audio indicators. The manufacturer specializes in piezoelectric alarms for demanding environments. The SC series is characterized by robust construction and compliance with industrial standards, serving as a core solution for machine tool and process control signaling.
