PB-2211

Alarms, Buzzers, And Sirens Overview

The PB-2211 is an externally driven piezoelectric buzzer manufactured by Soberton Inc. It operates within a voltage range of 3V to 28V DC and typically utilizes a 12V drive level with an 8mA current consumption. The device features a 22mm flange chassis design and produces an acoustic output of 85dB at a resonant frequency of 4.5kHz. Classified as a non-washable type, it serves as an audio indicator for various electronic systems requiring reliable audible signaling without integrated driver circuitry.

Alarms, Buzzers, And Sirens Feature Summary

• Externally driven piezoelectric transducer design
• Chassis mounting configuration with 22mm flange
• Non-washable construction suitable for standard assembly

Alarms, Buzzers, And Sirens Applications

• Electronic equipment status indication
• Alarm systems requiring audible alerts
• Industrial control panel signaling

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific datasheet version from Soberton Inc. to confirm electrical tolerances and mechanical dimensions. Ensure the application environment does not require washability, as this component is explicitly classified as non-washable. Confirm that the driving circuit can supply the required 8mA current at the operating voltage. Check for RoHS compliance status in the official documentation before procurement.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an external driver is available or preferred over integrated active buzzers. The wide voltage range allows flexibility in system power design. Consider the 85dB sound pressure level against ambient noise requirements. The flange mount style dictates the enclosure design constraints. Verify that the 4.5kHz frequency matches the desired auditory alert profile.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the PB Series of piezoelectric buzzers from Soberton Inc., which focuses on simple, robust audio indicators. The series includes various voltages and sizes, with the PB-2211 representing a mid-range option in terms of size and acoustic output. These components are distinct from active buzzers as they require an external square wave signal to operate.

Alarms, Buzzers, And Sirens Replacement Considerations

Direct substitutes must match the 22mm flange diameter, 4.5kHz frequency, and 85dB output. Verify pinout compatibility if applicable, though these are often two-terminal devices. Cross-reference with other Soberton PB models for similar form factors. Ensure replacement parts also meet the non-washable classification if used in standard PCB assembly processes.
