SC110Q

Overview

The SC110Q is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates at a nominal voltage of 12 VDC and produces an acoustic output level of approximately 95 dB at a distance of 10 cm. The device functions at a resonant frequency of 2.7 kHz. It features a square form factor with dimensions of 38 mm x 38 mm and a height of 14 mm. The unit utilizes a plastic case and includes built-in driving circuitry for direct connection to DC power sources.

Feature Summary

• Integrated oscillator circuitry enables direct DC drive without external components
• Piezoelectric transducer technology provides high reliability and long operational life
• Sealed plastic housing offers protection against environmental contaminants

Applications

• Industrial control panel signaling
• Appliance status indication
• Security system alerts

Procurement Notes

Verify the specific suffix codes on the component marking to ensure correct voltage and mounting configuration. Confirm that the required acoustic output meets the ambient noise conditions of the installation site. Check datasheet specifications for operating temperature range compatibility with the intended environment.

Selection Notes

Select this model when a self-contained, high-decibel audible alarm is required for 12 VDC systems. Consider the physical dimensions and mounting hole patterns to ensure fit within the enclosure design. Evaluate the frequency response against human hearing sensitivity for optimal alert effectiveness in the target application.

Part Context

This component belongs to the Sonalert series of piezoelectric buzzers known for robust performance in industrial environments. The SC110Q variant specifically targets applications requiring higher sound pressure levels compared to standard low-profile indicators. It represents a mature product line with established manufacturing standards for consistency.

Replacement Considerations

Cross-reference part numbers such as SC-110-Q or similar variants from the same manufacturer family. Ensure replacement units match the 12 VDC rating and 2.7 kHz frequency to maintain system compatibility. Verify mechanical footprint alignment before substitution.
