PB-4216-1

Overview

The Soberton PB-4216-1 is an externally driven piezo buzzer transducer designed for chassis or panel mounting. It operates within a voltage range of 3 to 20V DC, with a nominal rating of 12V. The device draws 8mA of current and produces a sound pressure level of 96dB at 12V measured from a distance of 10cm. Its operating frequency is 2.8kHz. The physical dimensions are 41.8mm in diameter and 16.3mm in height, featuring a flange design with wire leads for connection.

Feature Summary

• Externally driven piezo transducer technology
• Flange-style chassis or panel mount configuration
• Wire lead termination for direct circuit integration

Applications

• Audio indicator systems
• Chassis-mounted alert devices
• Panel-mounted status buzzers

Procurement Notes

Verify the specific ordering suffix to ensure correct voltage and acoustic specifications. Confirm RoHS compliance status if required by your manufacturing standards. Check datasheet revisions for any updates to mechanical drawings or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a high-output 96dB audible signal is required from a compact 41.8mm form factor. Ensure the driving circuit can supply the necessary 8mA current at the chosen operating voltage between 3V and 20V. Consider the flange mounting style for secure installation on panels or chassis surfaces.

Part Context

This part belongs to the Soberton PB-4216 series of piezo buzzers. Variants such as the PB-4216-2 share similar physical dimensions but may differ in electrical parameters or acoustic output. The series is characterized by non-washable type construction and external drive requirements, distinguishing it from self-exciting active buzzers.

Replacement Considerations

Direct substitutes must match the 41.8mm diameter, 16.3mm height, and 2.8kHz frequency. Verify that alternative parts support the 3-20V input range and provide comparable 96dB SPL at 10cm. Ensure the replacement maintains the flange mounting style and wire lead configuration for compatibility.
