Procurement Notes

Verify the specific suffix (U) against official documentation to confirm exact termination style or accessory inclusion. Confirm that the required mounting hole dimensions align with the specified 35.81 mm diameter. Ensure the application environment remains within the -20°C to 65°C operating temperature range. Validate that the 70 dB SPL meets the acoustic requirements for the intended installation location. Check for updated UL/UR certification status if required by local safety regulations.

Selection Notes

Select this component when a durable, waterproof chime alarm is required for harsh industrial environments. The wide voltage range allows compatibility with various control system power supplies. The IP68 rating makes it suitable for washdown areas or outdoor enclosures. Consider the 2.9 kHz tone and 70 dB output for appropriate audible alert levels. Verify that the panel mount form factor fits the available enclosure space.
