SC628AFPR

Overview

The SC628AFPR is an industrial-grade piezoelectric buzzer from the Mallory Sonalert SC series, designed for panel or flush mounting. It operates on a voltage range of 6 to 28 VDC and draws a rated current of 8 mA. The device emits a fast pulse tone at a frequency of 2900 Hz with a sound pressure level of 74 dBA. Physical dimensions are 1.69 inches in length and width, with a height of 1.41 inches. It utilizes screw terminals for connection.

Feature Summary

• Industrial-grade piezoelectric construction for reliable audio signaling
• Fast pulse tone generation capability for distinct alert patterns
• Screw terminal termination for secure electrical connections

Applications

• Industrial equipment fault indication
• Control panel status monitoring
• Safety system auditory alerts

Procurement Notes

Verify specific operational requirements against datasheet parameters before ordering. Confirm that the 6-28V DC input range aligns with the target power supply. Ensure mechanical mounting style matches the enclosure design. Check RoHS compliance documentation if required by project specifications. Validate lead times as availability may vary.

Selection Notes

Select this model when a moderate volume fast pulse signal is required for industrial environments. The 74 dBA output suits applications where high-intensity alarms are unnecessary. Consider the screw terminal interface for robust wiring needs. Compare against continuous tone variants if different alert patterns are preferred.

Part Context

Part of the Mallory Sonalert SC series, established since the 1960s as a foundational component for electronic sound alarms. The manufacturer specializes in high-performance acoustic devices for industrial, medical, and military sectors. This series represents a long-standing standard in panel-mounted audio indicators.

Replacement Considerations

SC628AHPR offers similar form factor but with higher intensity (87 dBA) and medium pulse characteristics.
