Alarms, Buzzers, And Sirens Procurement Notes

Verify that the specific part number matches the required electrical parameters, particularly the 12 VDC nominal voltage and 3.5 kHz frequency. Confirm that the flange mount style and wire lead termination are compatible with the target enclosure design. Ensure compliance with relevant environmental regulations such as RoHS requirements before finalizing procurement orders.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when an internally driven solution is preferred over external drive transducers to simplify circuit design. The 90 dBA output level is suitable for moderate noise environments. Consider the 30 mm diameter size constraint for panel cutouts. Compare against similar models like PK-27N35WQ if slight frequency variations are acceptable for the application.

Alarms, Buzzers, And Sirens FAQ

What is the difference between the PF-27N36WQ and PT series transducers?

The PF-27N36WQ is an internally driven buzzer containing its own oscillator, whereas PT series devices are external drive transducers requiring an external signal source.

Can the PF-27N36WQ operate on AC voltage?

No, the PF-27N36WQ is specified for DC operation only, with a rated voltage of 12 VDC and a range of 3 to 28 VDC.
