The LF 210-S, LF 510-S, LF 1010-S, and LF 2010-S Closed Loop ASIC based Hall effect current sensor measures DC, AC pulse currents' of 200, 500, 1000, 2000 ARMS (respectively)  nominal with galvanic isolation.

The LF 205-S/SP3 and LF 210-S/SP3  and Closed Loop ASIC based Hall effect current sensor measures DC, AC pulse currents' of 100 ARMS nominal with galvanic isolation.


  • Compact design
  • Panel mounted in various ways
  • Aperture: 15.6 mm (205-S/SP3), 15.59 mm (210-S and 210-S/SP3), 30 x 10 mm (510-S), 40 x 13 mm (1010-S), or 60 x 20 mm (2010-S) diameter for the primary conductor crossing
  • Excellent high accuracy at the level of Fluxgate technology but at the price of Hall effect

  • Exceptional offset drift of 0.1 % or 0.05 % (For 2010-S) of Ipn
  • Fast response time less than 0.5 µs
  • -40°C to + 85°C
  • External DC Dual supply ± 12 to ± 15V (For 205-S/SP3, 210-S/SP3, and 210-S), or ± 15 to ± 24V (For 510-S, 1010-S, and 2010-S)
  • Bipolar and insulated current measurement (For all except the 205-S/SP3)
  • Current output
  • Closed loop (compensated) current transducer
  • Panel mounting (For all except the 205-S/SP3)
