SC110D

Overview

The SC110D is a piezoelectric buzzer from the SC series, designed for panel mounting with a diameter of 42.85mm and maximum height of 35.54mm. It operates on AC or DC input within a voltage range of 30 to 120V. The device generates a single-tone sound at a frequency of 2kHz with a sound pressure level of 60dB @ 30V, 61cm. Power consumption ranges from 6 to 21mA. It features internal drive circuitry and utilizes threaded terminals or quick-connect tabs (0.250 inch) for connection. Operating temperature spans -30°C to 65°C.

Feature Summary

• Internal drive circuitry allows direct connection without external oscillators
• Piezoelectric technology ensures reliable acoustic output
• Versatile input compatibility supports both AC and DC power sources
• Panel mount design facilitates secure industrial installation

Applications

• Industrial alarm systems requiring audible warnings
• Control panels for machinery status indication
• Safety equipment notification units
• HVAC system fault signaling

Procurement Notes

Verify the specific suffix 'D' corresponds to the required terminal type and voltage rating. Confirm that the 30-120V AC/DC input matches the target application's power supply. Ensure panel cutout dimensions align with the 42.85mm diameter specification. Check for RoHS compliance requirements if applicable to the end product.

Selection Notes

Select this model when a high-voltage compatible, internally driven piezo buzzer is needed. Compare against lower voltage variants like the SC648CPNR if the system operates below 30V. Consider the 60dB SPL output for noise environment suitability. Verify that the 2kHz tone frequency meets regulatory or user preference standards for alert sounds.

Part Context

Part of Mallory Sonalert's SC series screw neck panel mount alarms. Designed for industrial environments where robustness and clear audio indication are critical. Shares physical dimensions with other SC series models but differs in electrical characteristics based on the numeric suffix indicating voltage range.

Replacement Considerations

Direct substitutes may include other SC series models with matching voltage ranges. Verify terminal configuration compatibility before swapping. Ensure replacement units meet the same cUL certification requirements for safety compliance in regulated installations.
