SC110KR

Overview

The SC110KR is a piezoelectric buzzer from the Mallory Sonalert SC series, designed for panel mounting. It features internal drive circuitry and accepts AC or DC input within a voltage range of 30 to 120V. The device operates at a frequency of 2kHz with a current draw between 6 and 20mA. It produces a sound pressure level of 60dB at 30V measured at 61cm. The unit utilizes screw terminals and quick-connect tabs (0.250 inch) for termination. Physical dimensions include a diameter of 42.85mm and a maximum installation height of 35.54mm. Operating temperature ranges from -30°C to 65°C.

Feature Summary

• Incorporates internal drive electronics for direct connection to power sources without external drivers.
• Supports both AC and DC input voltages across a wide industrial range.
• Features dual termination options including screw terminals and quick-connect tabs.

Applications

• Industrial control panels requiring audible status indication
• Machinery alarm systems for fault detection
• Electrical distribution equipment signaling

Procurement Notes

Verify the specific suffix 'KR' against the manufacturer's official documentation to confirm terminal configuration and certification status. Ensure the required operating mode matches the component specifications. Cross-reference the voltage rating with the application circuit to prevent damage. Confirm environmental ratings align with the installation site conditions.

Selection Notes

Select this component when an internal drive piezoelectric buzzer is required for high-voltage AC or DC applications. The 2kHz frequency provides distinct audibility in noisy environments. The dual termination style offers flexibility in wiring methods. Consider the physical size constraints and the need for panel mount installation before finalizing the design.
