Image of LEM GXS Series Compact, High-Bandwidth IC Sensors The GXS series from LEM offers compact, integrated current sensors built for accurate AC and DC current measurements in demanding industrial and automotive environments. Its architecture is optimized to reject external magnetic interference, allowing it to maintain stable performance even in electrically noisy settings.

With galvanic isolation and integrated signal conditioning, the GXS series ensures precise sensing through its low-resistance 1.2 mΩ primary conductor, minimizing power loss. Designed for versatility, it supports measurement ranges from 5 A to 60 A and operates reliably at temperatures up to +125°C, making it well suited for high-efficiency power electronics and control systems.
