SC628AHPR

Overview

The SC628AHPR is an industrial-grade piezoelectric buzzer from the Mallory Sonalert SC series. It operates on a voltage range of 6 to 28 VAC or VDC with a rated current of 16 mA. The device produces a medium volume pulse tone at a frequency of 4500 Hz, achieving a sound pressure level of 87 dBA. It features screw terminals for connection and is designed for panel mounting. The unit measures 43 mm in diameter and 1.41 inches in height, weighing 45 grams.

Feature Summary

• Piezoelectric technology with internal driver circuitry
• Industrial-grade construction for demanding environments
• Screw terminal connections for secure installation

Applications

• Industrial machinery fault indication
• Medical equipment status alerts
• Security system signaling

Procurement Notes

Verify the specific suffix against official Mallory Sonalert documentation to confirm electrical characteristics and termination style. Confirm RoHS compliance status through the manufacturer's certification documents prior to integration. Ensure the operating voltage matches the 6-28V AC/DC rating specified in the datasheet to prevent component damage.

Selection Notes

Select this model when a distinct 4500 Hz pulse tone is required for high-visibility audio warnings. The 87 dBA output provides clear audibility in noisy industrial settings. Verify that the panel cutout dimensions accommodate the 43 mm diameter housing and that the screw terminal interface aligns with the control wiring infrastructure.
