SC628-BTR

Overview

The SC628-BTR is a piezoelectric industrial alarm from the Mallory Sonalert SC series. It operates at a continuous tone frequency of 4.5 kHz with a sound pressure level of 89 dBA. The device is rated for 28 VDC and draws 23 mA. It features flat blade terminals for connection and is designed for panel mount installation. Physical dimensions are 43 mm in diameter and 1.41 inches in height.

Feature Summary

• Piezoelectric transducer technology for reliable acoustic signaling
• Continuous tone output optimized for industrial alerting
• Flat blade terminal configuration for direct circuit integration

Applications

• Industrial machinery status indication
• Equipment fault warning systems
• Control panel audio alerts

Procurement Notes

Verify the specific terminal type matches the design, as suffixes like BTR denote flat blades. Confirm voltage ratings align with the system power supply. Check RoHS compliance status if required by project specifications. Ensure panel cutout dimensions accommodate the 43 mm diameter housing.

Selection Notes

Select this model for applications requiring a high-pitched continuous alert. Compare current draw against available power sources. Consider alternative terminal styles if solder lugs or wire leads are preferred over flat blades. Verify environmental ratings if exposed to harsh conditions.

Part Context

Part of the long-standing SC628 series introduced in the 1960s, forming the foundation of Mallory Sonalert's product line. The SC series represents standard industrial-grade piezoelectric alarms known for durability and consistent performance across various sectors.
