LESR Series Closed-Loop Hall Effect Current Sensors

LEM USA LESR series current sensors are designed for high-precision electronic measurement of DC, AC, and pulse small currents ranging from 1.5 A_RMS to 50 A_RMS nominal, with galvanic isolation for enhanced safety and reliability. These sensors feature low offset drift and integrated primary conductors, ensuring consistent performance across a wide temperature range of -40°C to +105°C.

A key distinguishing feature of the LESR series is the inclusion of reference access on an additional pin, providing greater flexibility for system integration. Additionally, this product family seamlessly integrates with CASR sensors, ensuring compatibility across a broad range of industrial applications.

Leveraging closed-loop Hall effect technology, the LESR series delivers performance comparable to Fluxgate technology but at a lower cost, making it an ideal solution for applications that require both precision and cost efficiency. Designed for industrial environments, the LESR family combines accuracy, stability, and affordability, making it a trusted choice for current measurement solutions.
