SC110K

Overview

The SC110K is an industrial-grade piezoelectric alarm from the SC series, designed for panel mounting. It operates on AC or DC voltages ranging from 30 to 120V and draws a current of approximately 20mA. The device emits a short pulse tone at a frequency of 4.5 kHz with a sound pressure level of 80 dBA. It features screw terminals for connection and has a diameter of 42.85 mm.

Feature Summary

• Generates a distinct short pulse audible alert suitable for high-noise environments
• Operates reliably on both AC and DC power supplies within a wide voltage range
• Constructed with internal drive circuitry for direct connection without external components
• Designed for flush panel mounting with durable industrial housing

Applications

• Industrial machinery status indication
• Factory floor safety alarms
• Control panel warning systems
• Heavy equipment operational alerts

Procurement Notes

Verify the specific pulse rate requirements against the official datasheet, as rates may vary with supply voltage. Confirm that the installation environment meets the operating temperature specifications. Ensure the mounting hole dimensions align with the 42.85 mm diameter requirement. Check for necessary certifications such as UL or cUL for your specific regional compliance needs before finalizing the order.

Selection Notes

Select this model when a continuous tone is insufficient and a pulsing alert is required for attention-grabbing purposes. It is suitable for applications requiring operation from standard control voltages without additional drivers. Consider the SC110D if a continuous tone is preferred instead of a pulse. Evaluate the 80 dBA output level against ambient noise conditions to ensure audibility.

Part Context

This component belongs to the SC series of industrial alarms manufactured by Mallory Sonalert Products Inc. The series is characterized by robust construction and compatibility with various AC/DC input voltages. These devices are widely used in sectors requiring reliable audible signaling under harsh conditions.

Replacement Considerations

SC110HPR offers similar electrical characteristics but may differ in specific acoustic tuning or packaging details. Verify pinout and mounting dimensions before substitution.
