Overview
The PK-12N40PQ is a piezoelectric buzzer from Mallory Sonalert, designed for board-mount applications. It operates on a 12 VDC nominal voltage with a range of 3 to 15 VDC and draws 10 mA current. The device produces a continuous tone at 4.1 kHz with an 83 dB sound pressure level. Measuring 14 mm x 8 mm with a height of 7.5 mm, it features solder pin termination and through-hole installation.
Feature Summary
- Piezoelectric technology for reliable audible signaling
- Integrated internal driver circuitry for direct connection
- Compact form factor suitable for space-constrained designs
- Through-hole mounting with solder pin termination
Applications
- Electronic equipment status indicators
- Appliance control panels
- Industrial control systems
- Medical device alarms
Procurement Notes
Verify the specific ordering suffix against the official Mallory Sonalert datasheet to ensure correct acoustic and electrical characteristics. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before placing orders. Ensure compatibility with existing PCB layouts regarding terminal spacing and mounting requirements.
Selection Notes
Select this component when a compact, low-current piezoelectric indicator is required. The 12 VDC rating suits standard logic-level power supplies. Verify that the 83 dB SPL meets environmental noise requirements. Consider the 14x8mm footprint for PCB real estate constraints compared to larger industrial buzzers.
Part Context
This part belongs to the Mallory Sonalert audio indicators portfolio, specializing in piezoelectric transducers. The PK series typically offers board-mount solutions for general-purpose signaling. It complements larger bracket-mounted or panel-mounted alarm units within the manufacturer's comprehensive audio alerting product line.
Replacement Considerations
Consult the official Mallory Sonalert cross-reference documentation for verified substitute part numbers. Direct replacements must match voltage, frequency, and mechanical dimensions. Generic equivalents may lack certified performance data.
