94S4120LFLA

Overview

The DB Products 94S4120LFLA is a single piezoelectric buzzer designed for audible signaling applications. It operates at a nominal voltage of 12V DC and features a low-profile design with an ABS plastic housing. The component utilizes a long wavelength acoustic output to ensure clear sound projection over distance. This device is engineered for direct integration into electronic circuits requiring reliable audio feedback without the need for external drivers.

Feature Summary

• Single element piezoelectric construction for robust performance
• Low profile form factor suitable for space-constrained enclosures
• Long wavelength acoustic design for enhanced sound projection
• Direct drive capability from standard logic or power supplies

Applications

• Industrial control panel status indicators
• Medical equipment audible alarms
• Consumer appliance notification systems
• Automotive dashboard warning signals

Procurement Notes

Verify the specific acoustic pressure level and frequency tolerance against the official datasheet before procurement, as these parameters can vary significantly between manufacturing batches. Confirm that the 12V DC operating requirement aligns with the target system's power architecture. Ensure the mounting method accommodates the ABS housing dimensions to prevent mechanical stress on the piezoelectric element during assembly.

Selection Notes

Select this component when a compact, high-intensity audible signal is required in environments where space is limited. The long wavelength characteristic makes it suitable for applications needing sound to travel further than standard short-range buzzers. Consider the 12V DC rating to ensure compatibility with existing power rails, avoiding the need for additional voltage conversion stages.
