HTRS Series Compact Trackside Split-Core Sensors

LEM HTRS series compact split-core sensors deliver precision, safety, and seamless installation for smart grid and trackside applications

Image of LEM HTRS Series Compact Trackside Split-Core SensorsThe LEM HTRS product series offers a versatile solution for measuring DC, AC, and pulse currents from 10 A to 50 A, with built-in galvanic isolation for enhanced safety and performance. Engineered with innovative LEM technology, these split-core sensors overcome traditional accuracy challenges by ensuring optimal contact between core halves, enabling seamless installation on live power cables without interruption. Their compact form factor supports DIN rail or panel mounting with flexible 90° orientation options, while the 10 mm aperture and 3-pin standard connector simplify integration. Leveraging Hall effect technology, HTRS sensors are purpose-built for demanding smart grid and trackside environments, delivering precision and reliability where it matters most.

Features
  • Open loop current sensor using the Hall effect
  • Screw mounting or DIN rail option; both can rotate the positioning
  • Split-core design for easy installation
  • 10 mm aperture
  • Insulating plastic case recognized according to UL 94-V0
  • Reverse polarity protected
  • Easy mounting
