SC628JWR

Overview

The SC628JWR 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 VDC and features a slow warble tone at a frequency of 4.5 kHz. The device delivers a sound pressure level of 80 dBA with a current rating of 20 mA. Physical dimensions include a diameter of 33.35 mm and a length of 1.68 mm (0.066 in). Termination is achieved via screw terminals, and pin terminals are available as an option.

Feature Summary

• Piezoelectric transducer technology for reliable audio indication
• Slow warble tone generation for distinct alert signaling
• Industrial rugged construction suitable for harsh environments
• Screw terminal termination with optional pin terminal availability

Applications

• Industrial machinery fault warning systems
• Medical equipment status indicators
• Security and alarm system audio alerts
• Automotive and transportation control panels

Procurement Notes

Verify the specific suffix configuration against official Mallory Sonalert documentation to ensure correct tone and voltage ratings. Confirm that the required second unit specification for the J-series warble function is accounted for in the procurement plan. Check for RoHS compliance status and lead times directly with authorized distributors or the manufacturer before finalizing orders.

Selection Notes

Select this model when a distinct slow warble auditory signal is required within a 6-28 VDC operating range. Ensure the application supports panel mount installation with screw terminals. Consider the 80 dBA output level relative to ambient noise requirements. Verify if the optional pin terminal feature meets the wiring constraints of the target assembly compared to standard screw connections.

Part Context

The SC628JWR belongs to the SC series of industrial alarms manufactured by Mallory Sonalert Products Inc. This series represents a foundational line of electronic sound报警 devices originally introduced in the 1960s. The company, headquartered in Indianapolis, utilizes this series for robust audio indication across various sectors including industrial, medical, and consumer applications.
