PB-3212PK

Speakers Overview

The PB-3212PK is an 8 Ohm piezoelectric speaker manufactured by Mallory Sonalert Products Inc. It features a rated power of 0.1 W and a maximum power handling of 0.2 W. The device operates at a resonance frequency of 1250 Hz with an impedance of 8 ± 20% at 1500 Hz when measured at 1.0 V.

Speakers Feature Summary

• Piezoelectric transducer technology for audio output
• High efficiency sound pressure level of 85 dB at 1W/1M
• Compact design suitable for integrated audio applications

Speakers Applications

• Industrial alarm systems
• Audio indicators in control panels
• General purpose sound signaling devices

Speakers Procurement Notes

Verify the specific acoustic requirements against the 85 dB SPL rating at 1W/1M. Confirm that the 8 Ohm impedance matches the driving circuit capabilities. Ensure the 0.1 W rated power is sufficient for the intended operational duty cycle without exceeding the 0.2 W maximum limit.

Speakers Selection Notes

Select this component when a high-efficiency, low-power piezoelectric speaker is required. The 1250 Hz resonance frequency makes it suitable for distinct alert tones. Consider the physical dimensions and mounting style if space constraints exist within the target enclosure design.

Speakers Part Context

This part belongs to the Mallory Sonalert audio products lineup, specifically designed for reliable sound generation in industrial environments. It serves as a direct replacement for similar 8 Ohm piezo speakers requiring high efficiency and robust construction for continuous operation.

Speakers Replacement Considerations

Check datasheets for alternative 8 Ohm piezo speakers with comparable 85 dB SPL ratings. Verify that substitute parts maintain the same 1250 Hz resonance frequency and power handling limits to ensure acoustic performance consistency.
