SC628N-BTR

Alarms, Buzzers, And Sirens Overview

The SC628N-BTR is a piezoelectric industrial buzzer from the Mallory Sonalert SC series. It operates at a continuous tone frequency of 2.9 kHz with a sound pressure level of 103 dBA. The device is rated for 16 VDC and draws 22 mA. It features solder lug termination and panel mount installation. Dimensions are 43 mm diameter by 33 mm height, weighing approximately 45 g.

Alarms, Buzzers, And Sirens Feature Summary

• Piezoelectric construction for reliable audio indication
• High-intensity 103 dBA continuous output
• Solder lug terminals for direct circuit connection

Alarms, Buzzers, And Sirens Applications

• Industrial control panels
• Machinery status alarms
• Electrical safety indicators

Alarms, Buzzers, And Sirens Procurement Notes

Verify voltage compatibility carefully as this model is rated for 16 VDC, distinct from other SC series variants operating at higher voltages. Confirm that solder lug termination suits the assembly method. Check RoHS status in official datasheets as it may vary by production batch or region.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when high loudness is required at low voltage. Compare against 28 VDC models if system voltage differs. Ensure panel cutout dimensions match the 43 mm diameter requirement. Verify current draw fits power supply limits.

Alarms, Buzzers, And Sirens Part Context

Part of the classic Sonalert SC series known for rugged industrial performance. Differentiated by its specific 16 VDC rating and flat blade/solder lug terminal configuration compared to screw-terminal or wire-lead versions in the same family.

Alarms, Buzzers, And Sirens Replacement Considerations

SC628N is the base variant without specific terminal suffix. SC628N-BTR specifies the flat blade/solder lug style. Cross-reference with other 16 VDC piezoelectric buzzers if availability is limited.
