Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure compatibility with required voltage and acoustic specifications. Confirm that the pin configuration matches the target PCB layout. Check for any environmental ratings if the application involves extreme temperatures or humidity. Ensure the supply voltage aligns with the 12 VDC nominal requirement to prevent damage or insufficient performance.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a 12 VDC powered, 2100 Hz piezoelectric buzzer is required for PCB mounting. Consider the 85 dB acoustic output relative to the ambient noise environment. Evaluate the physical dimensions to ensure fit within the enclosure constraints. Verify that the through-hole pin spacing corresponds to the available board footprint.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the PB series of piezoelectric buzzers from Mallory Sonalert Products Inc. The series offers various voltage and frequency options.
