SC628DJR

Overview

The SC628DJR is an industrial-grade piezoelectric buzzer from the Mallory Sonalert SC series. It operates on a DC voltage range of 6 to 28 volts with a rated current of 15 mA. The device emits a slow pulse tone at a frequency of 1.9 kHz and achieves a sound pressure level of 95 dBA. It features screw terminals for connection and panel mount installation. The unit measures 43 mm in diameter by 33 mm in height and weighs 45 g.

Feature Summary

• Generates a distinct slow pulse acoustic signal for clear status indication
• Utilizes piezoelectric technology for reliable audio output
• Includes CUL approval certification for safety compliance

Applications

• Industrial equipment fault signaling
• Control panel status monitoring
• Safety alarm systems requiring certified components

Procurement Notes

Verify the specific suffix designation against official Mallory Sonalert documentation to confirm electrical characteristics and certification status. Ensure the required operating voltage aligns with the 6-28 VDC specification. Confirm that the screw terminal interface matches the target enclosure design. Cross-reference the CUL approval requirements with local regulatory standards before integration.

Selection Notes

Select this model when a slow pulse auditory alert is required for industrial environments. The 95 dBA output ensures audibility in moderate noise conditions. The screw terminal option facilitates secure wiring connections. Verify that the panel cutout dimensions accommodate the 43 mm diameter housing. Consider the 15 mA current draw for power supply capacity planning.

Part Context

The SC628DJR belongs to the SC series, a foundational line of electronic sound alarms introduced by Mallory Sonalert in the 1960s. This series established the standard for panel-mounted piezoelectric buzzers. The component represents a long-standing product line known for consistent performance and durability in various signaling applications.
