Image of LEM USA CASR Fluxgate Current Sensors LEM USA CASR current sensors are tailored for the electronic measurement of DC, AC, and pulsed current with galvanic isolation between the primary and secondary circuits. This product family features compact fluxgate-based current transducers, single-supplied (+5 V), and boasts low offset and gain drift, with a measuring range extending up to three times Ipn, and is designed for PCB mounting. CASR sensors feature three primary pins, catering to small current measurements from 2 A_RMS to 50 A_RMS nominal. Operating on closed-loop fluxgate technology, the CASR series is predominantly engineered for industrial applications.
