Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct voltage and lead length specifications. Confirm that the 24 VDC rating aligns with system power supplies. Check RoHS compliance documentation for regulatory requirements. Ensure mechanical mounting constraints accommodate the flange mount style and physical dimensions provided in the technical drawings.

Selection Notes

Select this component when a 24 VDC supply is available and a 400 Hz tone is required. Consider the 89 dB SPL for audible alerting needs. Evaluate the 147 mm wire leads for installation flexibility. Compare against other series members if different frequencies or voltages are necessary. Verify thermal limits for high-temperature environments.

Part Context

This model belongs to the PUI Audio industrial indicator series, designed for robust performance in demanding environments. The product line emphasizes durability and clear acoustic signaling. Variations within the series typically differ in voltage ratings, frequencies, and physical dimensions. This specific variant targets applications requiring stable 24 VDC operation.

Replacement Considerations

Direct substitutes must match the 24 VDC rating, 400 Hz frequency, and similar SPL. Check competitor models for equivalent piezoelectric technology and wire lead lengths. Verify mechanical compatibility including flange mount dimensions. Ensure operating temperature ranges overlap with application requirements.
