PB-12N23P-12Q

Overview

The PB-12N23P-12Q is a board-mount electromagnetic buzzer from Mallory Sonalert. It operates on a DC voltage range of 9 to 15VDC, with a nominal rating of 12V. The device produces a continuous tone at a frequency of 2.3kHz (2300Hz). Key electrical parameters include a sound pressure level of 85dB and a current draw of 50mA. It features solder pin termination for through-hole mounting. The physical dimensions are 12mm in diameter and 10mm in height.

Feature Summary

• Electromagnetic transducer technology for audible signaling
• Sealed construction design
• Internal driver circuitry for direct connection
• Through-hole PCB mounting capability

Applications

• Industrial control panel alarms
• Medical equipment status indicators
• Consumer appliance alerts
• Automotive system warnings

Procurement Notes

Verify the specific voltage variant required, as the PB series includes models for different supply voltages such as 4-7VDC or 9-15VDC. Confirm that the 12VDC nominal rating aligns with the target circuit's power supply specifications. Ensure the through-hole footprint matches the PCB layout constraints. Check RoHS compliance documentation if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a compact, internally driven electromagnetic buzzer is needed for low-voltage DC applications. The 12mm form factor suits space-constrained panels. Compare against piezoelectric alternatives if higher volume or different acoustic profiles are required. Ensure the 85dB output meets the ambient noise requirements of the installation environment.

Part Context

This part belongs to the PB series of audio indicators by Mallory Sonalert. The series offers various voltage ratings and acoustic outputs. The PB-12N23P-12Q specifically targets the 12VDC market segment with a constant tone output. It is distinct from the STA series which features larger piezoelectric units with bracket mounting.

Replacement Considerations

Mallory Sonalert provides cross-reference sheets for obsolete Murata buzzers. Verify compatibility with existing Murata parts if replacing legacy components. Ensure mechanical dimensions and pin configurations match the original design to avoid PCB modifications.
