    LF2010-S Closed-Loop Hall Effect Current Sensor – Setting a New Benchmark for High-Current Measurement in Industrial Applications


    LF2010-S Product Overview

    The LF2010-S is the flagship model of LEM’s LF xx10 series. It is a high-performance current sensor based on closed-loop Hall effect technology, specifically designed for high-precision current measurement in high-power scenarios up to 2000 A. The sensor supports bipolar, galvanically isolated current measurement and is suitable for DC, AC, and pulsed currents. It is widely used in motor drives, industrial power supplies, renewable energy, welding equipment, and rail transportation.

    The LF2010-S combines LEM’s 50+ years of expertise in electrical measurement with innovative ASIC technology, pushing the performance boundaries of traditional Hall effect sensors. It achieves precision levels previously attainable only by fluxgate technology, while maintaining the excellent response speed and noise immunity of closed-loop Hall effect sensors. It is the ideal choice for adding “accurate perception” to your industrial systems.

    Why Choose the LF2010-S?

    Among the many current sensors available, the LF2010-S stands out with three core values:

    High Accuracy – Closed-loop Hall effect technology delivers factory-calibrated ±0.2% accuracy, maintained over the full temperature range without need for field calibration.

    Rugged & Reliable – Wide operating temperature range from -40°C to +85°C, suitable for harsh industrial environments and rail applications.

    Flexible & Compatible – Multiple sub-models (e.g., /SP1, /SP23, /SP28, /SPA0) offer different connection and mounting options. Full compatibility with LF xx05 series enables seamless upgrades.
