Current Sensors Procurement Notes

Verify the specific suffix codes against official LEM documentation to ensure correct output type and mounting configuration. Confirm that the required supply voltage range aligns with your system's DC power availability. Check for updated datasheets regarding mechanical dimensions and thermal characteristics before finalizing integration into existing designs.

Current Sensors Selection Notes

Select this model when unidirectional current measurement up to 600A is required. Ensure the application does not demand bidirectional sensing, which would require a different series. Verify that the 4-20mA output matches the input requirements of the receiving PLC or controller. Consider the 32mm aperture size to ensure compatibility with the primary busbar or cable thickness.

Current Sensors Part Context
