LXSR Series
Closed Loop Hall effect current sensors performing at the level of Fluxgate technology without the added cost.
LXSR – Current sensors
The LXSR Series builds upon the LXS Series by offering reference voltage access, enabling greater flexibility for signal scaling and system calibration. These current sensors are designed for precise measurement of DC, AC, and pulsed currents up to 25A, with integrated galvanic isolation.
Optimized for industrial use, LXSR sensors combine low offset drift, integrated primary conductors, and reliable operation from -40 °C to +105 °C.
Leveraging closed‑loop Hall‑effect technology, the LXSR Series delivers high measurement performance comparable to Fluxgate solutions, without the added system cost.
