SC110R

Overview

The SC110R is a piezoelectric buzzer indicator manufactured by Mallory Sonalert Products Inc. It operates on an internal driver circuit with AC or DC input voltage ranging from 30 to 120V. The device produces a continuous tone at a frequency of 2.9kHz. Electrical characteristics include a supply current between 6 and 21mA. Acoustic performance is rated at 68dB sound pressure level measured at 30V and 61cm distance. The unit features panel mount installation with threaded terminals and quick-connect tabs sized at 0.250 inches (6.35mm). Physical dimensions are 1.687 inches in diameter and 1.399 inches maximum height.

Feature Summary

• Internally driven piezoelectric technology for direct connection to power sources
• Panel mount design utilizing both threaded terminals and quick-connect tabs
• Continuous tone output suitable for steady-state alarm indication

Applications

• Industrial control panels requiring audible status alerts
• Equipment monitoring systems for fault detection
• Safety warning indicators in machinery enclosures

Procurement Notes

Verify the specific suffix requirements against the official Mallory Sonalert datasheet to ensure correct acoustic and electrical specifications. Confirm that the operating environment falls within the -30°C to 65°C temperature range. Check for UL and cUL certification compliance if required by local safety regulations. Ensure the mounting hole diameter matches the 42.85mm specification. Validate terminal compatibility with existing wiring harnesses.

Selection Notes

Select this component when a high-voltage AC or DC compatible buzzer is needed without external drivers. Compare the 68dB SPL rating against ambient noise levels to ensure audibility. Consider the dual termination options for flexible wiring integration. Evaluate the physical size constraints against available panel space. Review alternative models in the SC series for different frequencies or sound pressure levels if requirements change.

Part Context

This part belongs to the SC series of industrial alarms and buzzers from Mallory Sonalert. The series is characterized by robust construction for demanding environments. The SC110 variant serves as the base model for various acoustic configurations. This specific unit represents the standard continuous tone configuration within that lineup.

Replacement Considerations

SC110DJR offers similar dimensions but provides a slow pulse tone instead of continuous output.
