PK-27A35EPQ

Overview

The PK-27A35EPQ is an industrial-grade piezoelectric buzzer manufactured by Mallory Sonalert Products Inc. It operates on a continuous tone at a frequency of 3.5 kHz with a sound pressure level of 95 dB. The device supports a voltage range of 3 to 24 VDC and is designed for panel mounting. Its physical dimensions are 37 mm in diameter and 24 mm in height, featuring wire lead termination.

Feature Summary

• Industrial-grade construction suitable for demanding environments
• Piezoelectric technology for reliable acoustic output
• Continuous tone operation mode
• Wide DC voltage compatibility

Applications

• Industrial machinery status indication
• Equipment fault alarms
• Process control audio alerts

Procurement Notes

Verify the specific voltage rating and current consumption requirements against the official Mallory Sonalert datasheet before integration. Confirm that the 3-24 VDC operating range aligns with the target power supply system. Ensure the panel cutout dimensions accommodate the 37 mm diameter and 24 mm height specifications for proper flange or panel mount installation.

Selection Notes

Select this component when a high-intensity 95 dB alert is required within a compact 37 mm form factor. The wide input voltage range allows flexibility in system design without needing additional regulation for the driver circuit. Consider the wire lead termination style for direct wiring connections rather than PCB mounting.

Part Context

This part belongs to the PK series of industrial buzzers from Mallory Sonalert. The series is characterized by robust piezoelectric elements designed for long-term reliability in harsh conditions. It serves as a standard solution for audible signaling where clear, loud tones are necessary for operator awareness.

Replacement Considerations

Consult official Mallory Sonalert cross-reference guides for verified substitutes. Generic replacements may not match the specific 95 dB SPL or 3.5 kHz frequency characteristics.
