PB-12N23P-01Q

Overview

The PB-12N23P-01Q is a board-mount electromagnetic buzzer manufactured by Mallory Sonalert Products Inc. It operates on a voltage range of 1.25V to 2.5VDC with a rated current of 25mA. The device produces a continuous tone at a frequency of 2.3kHz and achieves a sound pressure level of 80dB measured at 10cm from the source. It features through-hole solder pin termination and has physical dimensions of 12mm in diameter and height. The unit is sealed for environmental protection.

Feature Summary

• Electromagnetic transducer technology providing audible alerts
• Continuous tone operation mode for steady-state signaling
• Sealed construction designed for environmental durability
• Through-hole mounting configuration for PCB integration

Applications

• Electronic equipment status indication
• Consumer appliance audio feedback
• Industrial control panel signaling
• Portable device alert systems

Procurement Notes

Verify the specific voltage rating against your circuit design, as this component requires 1.25V to 2.5VDC. Confirm that the 2.3kHz continuous tone meets your acoustic requirements. Ensure the through-hole footprint matches your PCB layout. Check RoHS compliance documentation if required for your assembly process. Validate the sealed nature of the unit against your environmental exposure needs.

Selection Notes

Select this model when a low-voltage, compact electromagnetic buzzer is required for board-level integration. The 12mm form factor suits space-constrained designs. Consider the 80dB output sufficient for local alerts but not for noisy environments. Compare against piezoelectric alternatives if higher volume or different drive voltages are necessary. Ensure the 25mA current draw fits within your power budget constraints.

Part Context

This part belongs to the PB series of board-mount buzzers from Mallory Sonalert. It is an internally driven magnetic indicator designed for direct connection to logic circuits. The series offers various voltage and frequency options. This specific variant focuses on low-voltage operation suitable for battery-powered or low-power digital systems.

Replacement Considerations

The PB-12N23P-01Q may be replaced by other Mallory Sonalert PB series variants with matching voltage and frequency specifications. Cross-reference with PB-12N23P-05Q for higher voltage applications. Verify mechanical dimensions and electrical parameters before substitution. No direct substitute part numbers are publicly confirmed for identical performance.
