SC110J

Overview

The SC110J is a piezoelectric buzzer from Mallory Sonalert Products Inc., designed for industrial audio indication. It operates on an AC or DC input voltage range of 30 to 120V and features an internally driven indicator circuit. The device produces a slow pulse tone at a frequency of 2.9kHz with a sound pressure level of 68dB measured at 30V and 61cm. It utilizes screw terminal connections for secure wiring and supports panel mounting configurations.

Feature Summary

• Internally driven piezoelectric technology for reliable operation
• Slow pulse operating mode for distinct auditory alerts
• Compatible with both AC and DC power supplies within specified range

Applications

• Industrial machinery status indicators
• Control panel alarm systems
• Safety equipment auditory warnings

Procurement Notes

Verify the specific voltage rating and acoustic output requirements against the official datasheet before procurement. Confirm that the 30-120V AC/DC input range matches the target system's power supply capabilities. Ensure the panel mounting dimensions align with the enclosure design specifications to guarantee proper fit and secure installation during assembly.

Selection Notes

Select this component when a moderate sound level is sufficient for the application environment. The internal driver simplifies circuit design by eliminating external drive components. Consider the slow pulse mode if a less continuous but persistent alert is required compared to constant tone alternatives. Verify compatibility with existing panel cutouts and terminal access constraints.

Part Context

This part belongs to the SC series of industrial alarms, which are characterized by their robust construction and suitability for harsh environments. The series offers various frequencies and modes to suit different alerting needs while maintaining a consistent form factor for easy integration into standard control panels and industrial enclosures.

Replacement Considerations

Direct substitutes within the same series include SC110DJR and SC110FPR, though these may differ in frequency or sound pressure level. Verify that any replacement maintains the required voltage range and mounting style to ensure functional equivalence without mechanical modifications.
