PK-09N50PQ

Overview

The PK-09N50PQ is a piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a DC input voltage range of 9 to 16 volts and draws a supply current between 3 and 8 milliamperes. The device produces a continuous tone at a frequency of 5000 hertz with a sound pressure level of 90 decibels measured at a distance of 10 centimeters. It features a panel mount installation style with screw terminals for electrical connection. The unit has a circular diameter of 25 millimeters and an overall height of 14 millimeters. It is designed for operation within a temperature range of -20 degrees Celsius to +70 degrees Celsius.

Feature Summary

• Integrates internal driving circuitry for direct connection to power sources without external drivers.
• Provides high-intensity acoustic output suitable for audible alerting in various environments.
• Utilizes a compact cylindrical form factor optimized for standard panel cutouts.

Applications

• Industrial control panels requiring visual and auditory status indicators.
• Medical equipment alarm systems needing reliable audio alerts.
• Consumer appliance interfaces for user feedback signaling.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct voltage, frequency, and mounting configuration. Confirm that the terminal type matches the intended wiring method. Check for RoHS compliance requirements if applicable to the target market. Ensure the operating temperature range aligns with the environmental conditions of the final assembly. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a continuous tone indicator is required for panel-mounted applications. Consider the 9V to 16V DC operating range to ensure compatibility with existing system power supplies. Evaluate the 90dB SPL requirement against ambient noise levels to guarantee audibility. Assess the physical dimensions to confirm fit within the designated enclosure space. Verify that the screw terminal interface suits the available wiring infrastructure.
