Overview
The SC110DJ is a piezoelectric industrial buzzer from the Mallory Sonalert SC series, designed for panel mounting. It operates on an input voltage range of 30 to 120 VAC or VDC with a current rating of approximately 6 to 20 mA. The device produces a slow pulse tone at a frequency of 2 kHz (1900 Hz). It features screw terminals and quick-connect tabs for secure electrical connections. The unit has a diameter of 42.85 mm and a maximum height of 35.54 mm. It includes internal drive circuitry and holds cUL and UL certifications.
Feature Summary
- Internal drive circuitry enables direct connection to AC or DC power sources without external drivers.
- Piezoelectric technology generates a distinct slow pulse audio signal for alarm applications.
- Dual termination options provide flexibility with both screw terminals and quick-connect tabs.
Applications
- Industrial control panels requiring audible status alerts
- Machine tool safety interlock systems
- HVAC equipment fault indication
Procurement Notes
Verify the specific suffix against official Mallory Sonalert documentation to confirm the exact acoustic output and certification status. Ensure the required voltage range matches the system supply. Confirm that the panel cutout dimensions align with the specified 42.85 mm diameter. Check for any recent product change notices regarding terminal configurations or material composition updates.
Selection Notes
Select this model when a high-intensity audible alert is needed for industrial environments. The wide voltage compatibility simplifies integration into various control circuits. The robust construction supports operation in temperatures ranging from -30°C to 65°C. Consider the physical size constraints of the enclosure before finalizing the design.
Part Context
This component belongs to the SC series of industrial alarms manufactured by Mallory Sonalert Products Inc. The series is characterized by rugged construction suitable for demanding environments. The SC110DJ variant specifically offers a pulsed tone profile, distinguishing it from continuous tone models within the same family.
Replacement Considerations
SC110DPR provides a fast pulse alternative. SC110DJR offers similar specifications with potential minor manufacturing variations. SC110D delivers a continuous tone instead of a pulse. Verify mechanical fit and electrical requirements before substituting.
