Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct electrical and mechanical specifications. Confirm RoHS compliance status and mounting requirements prior to integration. Cross-reference the part number with authorized distributors to validate authenticity and current production status.
Selection Notes
Select this component when a high-decibel constant tone is required for panel-mounted applications. Ensure the operating voltage falls within the 3-24 VDC range. Verify that the 30 mm diameter and 16 mm height fit the designated enclosure space. Consider the wire lead termination method for circuit connectivity.
Part Context
This part belongs to the PK series of industrial-grade audio indicators from Mallory Sonalert. The series is known for robust performance in demanding environments. Similar models include PL-27A35WQ and PK-27N35WQ, which offer variations in sound patterns and decibel levels while maintaining comparable form factors.
Replacement Considerations
Consult official substitution guides for compatible alternatives. Verify pinout and dimensional compatibility before replacing existing units. Ensure replacement parts meet the same voltage and acoustic requirements.
