Image of LEM USA CKSR Series Fluxgate Current Sensors LEM USA CKSR series encompasses current sensors tailored for the electronic measurement of DC, AC, and pulsed current with galvanic isolation between the primary and secondary circuits. This family features compact fluxgate-based current transducers, single-supplied (+5 V), and boast low offset and gain drift, with a measuring range extending up to three times Ipn, and is designed for PCB mounting. CKSR sensors have four primary pins, with the CKSR 75-NP version featuring five primary conductors, along with high creepage and clearance distances, supporting small current measurements from 1.5 A_RMS to 75 A_RMS nominal. Operating on closed-loop fluxgate technology, CKSR sensors are predominantly engineered for industrial applications.
