Overview
The SC110DJR is a piezoelectric industrial buzzer from the SC series by Mallory Sonalert. It operates on 30 to 120 VAC or DC with a current draw of 6 to 20 mA. The device produces a slow pulse tone at 2 kHz with a sound pressure level of 60 dB at 30V, 61cm. It features panel mount installation via screw terminals and quick-connect tabs (0.250 inch). Certified by cUL and UL, it functions within -30°C to 65°C.
Feature Summary
- Piezoelectric technology for reliable audio indication
- Internal driver circuitry for direct AC/DC operation
- Dual termination options including screw terminals and quick-connect tabs
- Industrial-grade construction with cUL and UL certifications
Applications
- Industrial machinery fault signaling
- Control panel status indication
- Safety system alarm alerts
- Equipment monitoring systems
Procurement Notes
Verify the specific suffix requirements against the official Mallory Sonalert datasheet to ensure correct voltage and tone configuration. Confirm that the operating environment falls within the specified temperature range of -30°C to 65°C. Check for any recent Product Change Notices regarding terminal types or housing materials before finalizing procurement specifications.
Selection Notes
Select this model when a slow pulse audible alert is required for 30-120V circuits. The 60 dB output suits applications where moderate volume is sufficient. Ensure the mounting panel allows for the 42.85 mm diameter footprint. Compare against the SC110DPR if a faster pulse rate is needed, or the SCH110NJR for higher sound pressure levels in noisy environments.
Part Context
Part of the SC series, designed for general industrial use. The SC110DJR variant specifically denotes the slow pulse tone characteristic. It shares the standard 43 mm diameter form factor common to the SC family, allowing for consistent panel cutout designs across different tone and voltage configurations within the same product line.
Replacement Considerations
SC110DPR offers a fast pulse alternative within the same series. SC110D provides a continuous tone option. For higher volume requirements, consider the SCH110NJR series. Verify electrical compatibility and physical dimensions before substituting.
