PB-4216-2

Overview

The PB-4216-2 is an externally driven piezo transducer manufactured by Soberton Inc. It operates within a voltage range of 3 to 20V, with a rated voltage of 12V. The device draws 8mA and produces a sound pressure level of 100dB at 12V, with a resonant frequency of 2.8kHz. It features a flange mount design with wire leads for panel installation. The unit measures 41.8mm in diameter and 16.30mm in height. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Externally driven piezoelectric construction
• Flange mounting configuration with wire leads
• High acoustic output capability

Applications

• Panel-mounted audio indicators
• Alarm systems requiring high decibel output
• Industrial control panel signaling

Procurement Notes

Verify the specific ordering suffix to ensure correct lead length and connector type if applicable. Confirm RoHS compliance status through official documentation before integration. Check datasheet for exact mechanical tolerances to ensure proper panel cutout dimensions. Validate electrical specifications against system requirements to prevent overvoltage damage.

Selection Notes

Select this component when a high-volume, low-cost piezo indicator is required for panel mounting. The 100dB output makes it suitable for noisy environments where audible alerts are critical. Ensure the driving circuit can supply the necessary current without exceeding the voltage limits. Consider the physical size constraints of the enclosure during the design phase.

Part Context

This part belongs to the PB-4216 series of piezo buzzers from Soberton Inc., formerly Mallory Sonalert Products. The series is known for robust construction and reliable performance in industrial applications. The PB-4216-2 variant specifically denotes the flange mount style with wire leads, distinguishing it from other mounting options in the family.

Replacement Considerations

Direct substitutes may include other 12V piezo buzzers with similar 41.8mm diameter and flange mounting. Verify that replacement parts match the 100dB @ 12V acoustic output and 2.8kHz frequency. Ensure the replacement component supports the same 3-20V operating range and -40°C to +85°C temperature rating.
