SC628ANP

Overview

The SC628ANP is a piezoelectric industrial buzzer manufactured by Mallory Sonalert. It operates on a voltage range of 6 to 28 VAC or VDC with a rated current of 30 mA. The device produces a continuous tone at a frequency of 2.9 kHz and achieves a sound pressure level of 80 dBA. Designed for panel mounting, it features screw terminals for connection. The unit measures 43 mm in diameter and 33 mm in length, weighing approximately 45 g.

Feature Summary

• Piezoelectric technology for reliable audio signaling
• Supports both AC and DC power inputs within the specified range
• Industrial-grade construction suitable for demanding environments

Applications

• Industrial machinery status indication
• Control panel alarm systems
• Equipment fault warning signals

Procurement Notes

Verify the specific suffix requirements for your application, as variants like SC628ANPR offer CUL approval and different acoustic profiles. Confirm terminal type compatibility during integration. Check RoHS status if environmental compliance is required for your region. Ensure the operating voltage matches the 6-28V specification to prevent damage.

Selection Notes

Select this model for applications requiring a constant tone audible at 80 dBA. It is suitable where screw terminal connections are preferred over wire leads. Consider the SC628NLR variant if wire leads are needed instead of screws. Evaluate the SC628MH series for higher ruggedness or different frequencies.

Part Context

This component belongs to the SC series of industrial alarms from Mallory Sonalert. The series is known for robust piezoelectric design and wide voltage tolerance. It serves as a standard solution for visual-audio alerting in heavy industry and commercial equipment.

Replacement Considerations

SC628ANPR is a direct variant offering CUL approval.
