PB-12N23P-09Q

Overview

The PB-12N23P-09Q is a magnetic buzzer indicator manufactured by Mallory Sonalert Products Inc. It operates on a 9 VDC supply with a current draw of 50 mA and produces a continuous tone at 2.3 kHz. The device delivers an acoustic output of 85 dB measured at 10 cm from the source. Designed for through-hole mounting, it features PC pin termination and measures 12 mm in diameter with a height of 10 mm.

Feature Summary

• Internally driven electromagnetic design requiring no external oscillator circuitry
• Continuous tone generation capability for steady-state audio indication
• Through-hole construction with standard PC pin termination for board integration

Applications

• Electronic equipment status indication
• Control panel audio alerts
• Appliance signaling systems

Procurement Notes

Verify the specific voltage rating matches the target circuit requirements before procurement. Confirm that the through-hole footprint dimensions align with the printed circuit board layout. Ensure the acoustic output level meets the environmental noise constraints of the intended installation site.

Selection Notes

Select this component when a simple, internally driven audible alert is required for low-voltage DC applications. The 9 VDC specification distinguishes it from other variants in the series. Consider the physical size constraints as the unit occupies a 12 mm diameter space on the assembly.

Part Context

This part belongs to the PB series of board-mount buzzers from Mallory Sonalert. The series offers various voltage options including 5 V, 9 V, and others, all sharing similar compact form factors. These devices are designed for direct integration into electronic assemblies without additional driver components.

Replacement Considerations

Cross-reference with other Mallory Sonalert PB series parts such as PB-12N23P-05Q or PB-12N23P-12Q if voltage differences are acceptable. Verify mechanical compatibility and acoustic performance specifications before substituting.
