Procurement Notes
Verify the specific suffix code (e.g., AN, ANJ, ANPR) as these denote distinct electrical characteristics such as tone type and loudness. Confirm voltage compatibility within the 6-28 VAC/DC range. Check for required certifications like CUL if applicable to your region. Ensure panel cutout dimensions match the 43 mm diameter specification before ordering.
Selection Notes
Select this component when a slow pulse alert is required for low-voltage industrial environments. Compare sound pressure levels against ambient noise requirements. Consider the screw termination method for vibration resistance. Evaluate the physical dimensions against available panel space constraints.
Part Context
This part belongs to the SC series of industrial buzzers manufactured by Mallory Sonalert Products Inc. The series offers various configurations for different voltage ranges and acoustic outputs. The SC628AN specifically targets applications requiring moderate volume alerts with a pulsing signal pattern.
FAQ
What is the operating voltage range for the SC628AN?
The SC628AN operates within a voltage range of 6 to 28 VAC or DC.
Does the SC628AN use internal or external drive circuitry?
The SC628AN is a piezoelectric buzzer that typically requires an external driver circuit to generate the pulse tone, unlike some self-contained active buzzers.
