SC628ANPR

Overview

The SC628ANPR is an industrial-grade piezoelectric buzzer from the Mallory Sonalert SC series, designed for panel mounting. It operates on a voltage range of 6 to 28 VAC or VDC with a rated current of 30 mA. The device produces a fast pulse tone at a frequency of 2.9 kHz, achieving a sound pressure level of 95 dBA. It features screw terminals for connection and measures 43 mm in diameter by 1.41 inches in height. The unit weighs 45 grams and holds CUL approval.

Feature Summary

• Industrial-grade piezoelectric construction for reliable audio signaling
• Fast pulse tone generation optimized for immediate attention alerts
• CUL approved certification ensuring compliance with safety standards
• Screw terminal end type providing secure electrical connections

Applications

• Industrial machinery fault indication
• Control panel status monitoring
• Safety system alarm signaling

Procurement Notes

Verify that the specific application requires the fast pulse characteristic and 95 dBA output level. Confirm compatibility with the 6-28 VAC/VDC supply range and ensure the panel cutout accommodates the 43 mm diameter. Check for required CUL certification documentation if mandated by local regulations. Ensure screw terminal wiring methods align with the installation environment constraints.

Selection Notes

Select this model when high-intensity audible alerts are necessary in industrial settings. The fast pulse mode distinguishes it from continuous tone variants like the SC628NLR. Consider the 30 mA current draw against available power supplies. The screw terminal interface suits applications requiring robust mechanical connections compared to quick-connect options found in other series members.

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 medical, military, and industrial sectors. This specific part represents a standard industrial alert solution within their extensive portfolio of piezoelectric indicators.

Replacement Considerations

SC628ANJ offers a slow pulse variant with lower sound pressure. SC628MH provides a continuous tone option. SC628NDPR delivers higher volume but differs in physical dimensions.
