GXM Series

High-isolation SO10 packages with optional very low primary conductor resistance 

The GXM Series is a LEM integrated current transducer designed for precise measurement of both AC and DC currents in industrial and automotive contexts. The sensor features effective rejection of external fields originating from noisy environments. 

Advanced temperature compensation algorithms ensure high accuracy up to 150°C.

With an ultra-low primary conductor resistance of only 0.27 mΩ for GXM ANC (500 uOhm for GXM AN, the device achieves superior thermal performance while minimizing power loss, and includes 20kA lightning test standard.

The GXM Series supports current measurements with IPM ranging from 50 to 200A. Externally settable overcurrent detection can be selected, offering fast, reliable, and adaptable protection solutions. 

Furthermore, galvanic insulation between the primary and secondary sides eliminates the need for additional insulation, reducing both system footprint and overall cost.
