Overview
The SC110FKR is a piezoelectric buzzer from the Mallory Sonalert SC series, designed for panel mounting with screw terminals. It operates on 30 to 120 VAC/DC input and draws 4 to 13 mA of current. The device emits a short pulse tone at a frequency of 2900 Hz with a sound pressure level of 55 dB @ 30V, 61cm. It features an internal driver circuit and functions within a temperature range of -30°C to +65°C. The unit has a diameter of 42.85mm and a maximum installation height of 35.54mm.
Feature Summary
- Integrates an internal driver circuit for direct AC or DC connection without external oscillators.
- Features a piezoelectric transducer generating a distinct short pulse acoustic signal.
- Constructed for robust panel mounting using screw terminal connections.
Applications
- Industrial control panel status indication
- Machine tool alarm signaling
- HVAC system fault alerts
Procurement Notes
Verify the specific suffix 'KR' against the manufacturer's latest datasheet to confirm terminal type and environmental ratings. Ensure the operating voltage matches the 30-120V AC/DC specification. Confirm that the 55dB SPL meets the required audibility standards for the intended installation environment.
Selection Notes
Select this model when a low-current, internally driven piezoelectric indicator is required for high-voltage AC/DC systems. The SC series offers a compact form factor suitable for standard panel cutouts. Consider the 2900Hz frequency for optimal human perception in noisy industrial settings compared to lower frequency alternatives.
Part Context
This component belongs to the SC series of industrial alarms and buzzers manufactured by Mallory Sonalert Products Inc. The series is characterized by its versatility in handling both AC and DC inputs while maintaining a consistent physical footprint. The SC110FKR represents a specific configuration within this line, optimized for pulse signaling applications.
Replacement Considerations
SC110FJ: Similar SC series piezo buzzer with quick connect terminals instead of screw terminals. SC110HPR: Fast pulse variant with higher SPL and different frequency characteristics. Verify electrical compatibility and mechanical mounting dimensions before substitution.
