Current Sensors Procurement Notes

Verify the specific suffix 'SW' against the official LEM datasheet to confirm pinout and connector configuration. Ensure the ordering part number matches the required output signal type and supply voltage specifications. Cross-reference the package dimensions with your PCB layout to guarantee mechanical fitment before procurement.

Current Sensors Selection Notes

Select this model when precise measurement of high peak currents is required alongside a standard nominal rating of 100 A. Consider the open-loop architecture for cost-sensitive designs where moderate accuracy suffices. Verify that the operating temperature range aligns with the thermal environment of the target application.
