Overview
The SC110DPR is an industrial-grade piezoelectric buzzer manufactured by Mallory Sonalert. It operates on a voltage rating of 30-120V AC/DC with a current draw of 20 mA. The device produces a fast pulse tone at a frequency of 1900 Hz and achieves a sound pressure level of 75 dBA. It features screw terminals for connection and is designed for panel mounting. Physical dimensions include a diameter of 43 mm, a length of 42.85 mm, and a height of 35.56 mm (1.41 in). The unit weighs 45 g and holds cUL approval.
Feature Summary
- Piezoelectric technology providing reliable audio signaling
- Internal driver circuitry for direct AC or DC operation
- Industrial construction suitable for demanding environments
- Certified compliance with safety standards
Applications
- Industrial machinery status indication
- Control panel alarm systems
- Electrical equipment fault alerts
- Safety warning devices in manufacturing settings
Procurement Notes
Verify the specific suffix DPR to confirm the fast pulse tone characteristic and 75 dBA output level. Ensure the operating voltage range of 30-120V matches the system supply. Confirm that panel mount installation with screw terminals fits the enclosure design. Check for required certifications such as cUL for the target market.
Selection Notes
Select this model when a moderate volume indicator is required for high-voltage industrial applications. The internal driver simplifies integration by eliminating external components. Compare against continuous tone variants if a steady alert is preferred. Consider physical size constraints given the 43 mm diameter requirement.
Part Context
This component belongs to the SC series of industrial alarms from Mallory Sonalert. The series offers various tones and voltages for different industrial needs. The SC110DPR specifically addresses requirements for pulsed alerts in heavy-duty environments.
