LES Series Closed-Loop Hall Effect Current Sensors

LEM USA LES series closed-loop Hall effect current sensors provide cost-effective current sensing solutions for a wide range of industrial applications

Image of LEM USA LES Series Closed-Loop Hall Effect Current SensorsLEM USA LES series current sensors are expertly designed for the precise electronic measurement of DC, AC, and pulse small currents ranging from 1.5 ARMS to 50 ARMS nominal, while maintaining galvanic isolation. Engineered for high accuracy and stability, these sensors feature low offset drift and integrated primary conductors, ensuring optimal performance across a broad temperature range of -40°C to +105°C.

A key advantage of the LES series is its seamless integration with CAS sensors, providing enhanced compatibility and flexibility across various industrial applications. Utilizing closed-loop Hall effect technology, the LES family delivers performance comparable to Fluxgate technology but at a significantly lower cost, making it an ideal choice for cost-sensitive yet high-precision applications.

With robust construction and cutting-edge technology, the LES family is tailored to meet the demanding requirements of industrial environments, offering accuracy, reliability, and cost efficiency in current measurement solutions.
