- Continuous tone operation at 3.5 kHz
- Wide DC voltage operating range
- Flange mount design with wire leads
Applications
- Industrial machinery status indicators
- Control panel alarm systems
- Equipment fault detection alerts
Procurement Notes
Verify the specific suffix requirements against the official Mallory Sonalert datasheet to ensure correct acoustic and electrical characteristics. Confirm that the flange mount style and wire lead termination match the target assembly interface. Check RoHS compliance documentation for regulatory adherence in the intended market.
Selection Notes
Select this component when a compact, high-intensity audible alert is required for industrial environments. The wide voltage tolerance allows flexibility in power supply design. Ensure the mounting hole size accommodates the 30 mm diameter flange and that the enclosure allows for adequate sound projection.
Part Context
This part belongs to the PK series of piezoelectric buzzers, which are engineered for durability and consistent performance in demanding conditions. The series offers various mounting styles and acoustic outputs to suit different industrial notification needs.
Replacement Considerations
Consult the manufacturer's cross-reference guide for verified substitutes. Ensure any replacement matches the 3.5 kHz frequency, 90 dBA output, and 30x16 mm form factor.
