PK-27N35PSQ

Overview

The PK-27N35PSQ is a piezoelectric buzzer from the PK series by Mallory Sonalert Products Inc. It operates on a DC input with a rated voltage of 12 V and a current consumption of 15 mA. The device produces a slow pulse tone at a frequency of 3.5 kHz with a sound pressure level of 90 dB. Designed for flush mounting, it features wire lead termination and measures 30 mm in diameter and 16 mm in height.

Feature Summary

• Integrates internal drive circuitry for direct connection to power sources without external drivers.
• Generates an audible slow pulse signal suitable for status indication or alarm functions.
• Constructed with a compact flange design intended for secure panel or board installation.

Applications

• Industrial control panels requiring visual and auditory status alerts
• Electronic equipment housing needing compact flush-mounted indicators
• Automotive instrumentation dashboards for system warnings

Procurement Notes

Verify the specific suffix codes against the manufacturer's official part numbering guide to ensure correct voltage, tone, and mounting configurations. Confirm RoHS compliance status and environmental certifications required for your target market before finalizing orders. Cross-reference the DigiKey or Mouser catalog numbers to validate availability and standard packaging details.

Selection Notes

Select this component when a low-profile, internally driven piezoelectric indicator is required for flush mounting applications. Ensure the operating environment supports the specified voltage range and that the 3.5 kHz slow pulse frequency meets the acoustic visibility requirements of the enclosure. Compare dimensions against available panel cutouts to guarantee proper fitment during assembly.
