PB-2418-2

Overview

The PB-2418-2 is a piezoelectric buzzer manufactured by Soberton Inc., designed for through-hole mounting applications. This externally driven transducer operates at a nominal voltage of 12V with a current consumption of 8mA. It produces an acoustic output of 90dB measured at a distance of 10cm and functions at a resonant frequency of 3.7kHz. The component features a 24mm diameter housing and utilizes PC pins for board connection, ensuring reliable integration into electronic circuits requiring audible signaling.

Feature Summary

• Externally driven piezoelectric transducer design
• Through-hole mounting configuration with PC pins
• Non-washable type construction

Applications

• Alarm systems
• Audible signaling in embedded electronics
• Industrial control panels

Procurement Notes

Verify the specific ordering suffix to confirm the exact electrical characteristics and mechanical dimensions match the design requirements. Ensure that the non-washable nature of the component aligns with the intended manufacturing process and environmental exposure conditions during assembly.

Selection Notes

Select this component when a high-output audible indicator is required for 12V logic or power rails. Consider the 90dB acoustic level and 3.7kHz frequency for human audibility. Evaluate the through-hole footprint compatibility against the target PCB layout constraints before finalizing the bill of materials.

Part Context

This part belongs to the audio product category, specifically within the alarms, buzzers, and sirens segment. It serves as a discrete active sound generation element for circuit boards, distinct from integrated microcontroller solutions, providing direct acoustic feedback upon voltage application.

Replacement Considerations

Cross-reference with other 12V piezo buzzers featuring similar 90dB output and 3.7kHz resonance. Verify mechanical footprint compatibility and pin configuration before substituting with alternative manufacturers' components.
