PB-12N32MP-12Q

Overview

The PB-12N32MP-12Q is a self-contained electromagnetic buzzer manufactured by Mallory Sonalert Products Inc. It operates on a rated DC voltage of 12V, with an acceptable input range of 9 to 15V. The device draws a current of 50mA and produces a continuous tone at a frequency of 3.2kHz. It achieves a sound pressure level of 85dB when measured at a distance of 10cm. The unit features through-hole PC pin termination for panel or board mounting. Its physical dimensions are 12mm in diameter and 8.20mm in height. The operating temperature range extends from -20°C to 70°C.

Feature Summary

• Self-contained internally driven magnetic technology eliminates the need for external driver circuitry.
• Continuous single-tone acoustic output provides consistent audible signaling.
• Through-hole PC pin construction facilitates secure mechanical attachment to printed circuit boards.

Applications

• Industrial control panel status indication
• Electronic equipment alarm systems
• Appliance operational feedback signaling

Procurement Notes

Verify that the specific part number matches the required electrical specifications, particularly the 12V DC rating and 3.2kHz frequency. Confirm that the through-hole PC pin pitch aligns with the target PCB layout. Ensure the environmental conditions, including the -20°C to 70°C operating range, meet the application requirements. Check for compliance certifications such as RoHS if mandated by the project standards. Validate the acoustic performance metrics against system noise levels.

Selection Notes

Select this component when a self-exciting, high-intensity audible indicator is required for 12V DC systems. The internal driver simplifies circuit design by removing the need for additional transistors or oscillators. Consider the 85dB output level for environments requiring clear auditory alerts. The 12mm diameter form factor suits applications with limited panel space. Evaluate the through-hole mounting option for robust mechanical stability compared to surface-mount alternatives.

Part Context

This component belongs to the PB series of electromagnetic buzzers from Mallory Sonalert. These devices are designed for industrial-grade audio indication. The series offers various voltage and frequency combinations to suit different signaling needs. The PB-12N32MP-12Q specifically targets 12V DC applications requiring a mid-frequency continuous tone. It represents a standard solution for basic audible alerting in electronic assemblies.

Replacement Considerations

Cross-reference with other Mallory Sonalert PB series parts offering similar 12V DC ratings and through-hole packaging. Verify that substitute components match the 3.2kHz frequency and 85dB acoustic output. Ensure the replacement maintains the same PC pin configuration and dimensional constraints for direct fitment without PCB redesign.
