Procurement Notes

Verify the specific part number 11806827 against official WERMA documentation to confirm electrical ratings and mechanical dimensions. Ensure the application environment meets the IP30 protection requirements. Confirm that the mounting hole size corresponds to the M28 thread specification. Check for RoHS compliance if required by project specifications. Validate that the operating temperature range aligns with the installation site conditions.

Selection Notes

Select this component when a continuous tone signal is required for 115V systems. Consider the 90dB output level relative to ambient noise levels. Evaluate the M28 mounting requirement against existing panel cutouts. Assess the need for internal driving capabilities versus external drivers. Verify compatibility with the intended control voltage source before integration.
