High-power sensor, designed for easy installation on existing power cables.

High-power sensing made easy

HTRS, COMPACT SPLIT-CORE FOR TRACKSIDE MARKET

LEM engineers designed HTRS as the next generation of split-core sensors for the trackside market. It combines high-accuracy with ultra-compactness and an easy and flexible mounting.

The unique technology used by LEM, removes inaccuracy issues of the split-core sensors that originate in the imperfect contact between the 2 core halves. 

The HTRS range covers from 1 A to 100 A (max) primary current sensing. It can be mounted either using screws or using an add-on Din-Rail connector. And in both cases, it allows different orientations of the sensor, with a 90° step.
