PB-3214NL

Overview

The PB-3214NL is an externally driven piezoelectric transducer manufactured by Soberton Inc. It operates at a rated voltage of 12 V with a current consumption of 15 mA. The device produces a sound pressure level of 90 dB at the rated voltage and distance. Its resonant frequency is 3700 Hz (3.7 kHz). The unit features a 32 mm flange design for panel mounting and utilizes wire leads for termination. It does not include a built-in drive circuit.

Feature Summary

• Externally driven piezoelectric transducer design
• Panel mount configuration with integrated flange
• Wire lead termination for direct connection

Applications

• Industrial alarm systems
• Equipment status indicators
• Control panel audio feedback

Procurement Notes

Verify that the application circuit provides external driving signals, as this component lacks internal drive electronics. Confirm mechanical compatibility with the 32 mm mounting hole diameter. Ensure the operating environment does not require washable components, as this model is not washable. Validate that the 12 V supply matches the system voltage to maintain specified acoustic performance.

Selection Notes

Select this part when a high-output 90 dB audible signal is required from a compact 32 mm form factor. Choose this model if the design allows for external driver integration rather than requiring a self-contained active buzzer. Consider the wire lead termination method for assembly processes compatible with through-hole or direct soldering connections.

Part Context

This component belongs to the PB Series of piezo buzzers from Soberton Inc. The series offers various voltage and frequency options within a standardized flange package. The PB-3214NL specifically targets applications needing robust acoustic output at 12 V operation without the complexity of active driver circuits.

Replacement Considerations

Cross-reference with other Soberton PB series models sharing the 32 mm flange dimension. Verify that substitute parts match the 12 V rating and 3700 Hz frequency to ensure identical acoustic characteristics. Check termination types to confirm wire lead compatibility with existing PCB or harness designs.
