Split-core open-loop Hall Effect current sensors for trackside installations, measuring DC, AC, and pulse currents. The split core clamps around an existing power cable without disconnection. LEM’s proprietary technology eliminates the contact accuracy issues common to standard split-core designs — cable position deviation is less than 0.03% — giving consistent performance regardless of conductor placement within the aperture. Screw plate or DIN rail adapter mounting, both allowing 2 orientations relative to the current direction; 3-pin standard connector; UL94-V0 insulating plastic case; reverse polarity protected; no insertion losses.

Applications include points condition monitoring, signal light indication, battery-supplied equipment, and UPS systems in trackside environments.
