LAH Board Mount Current Sensors

LEM LAH Board Mount Current Sensors are designed for precise measurement of DC, AC, and pulse currents, with nominal values ranging from 8A to 125A RMS. These closed-loop Hall effect sensors come in a compact design with an integrated primary conductor. The PCB mounting capability for both primary and secondary circuits enhances the ease of integration of these transducers. The LAH current sensors offer galvanic isolation, excellent accuracy, and fast response time, which makes them an ideal choice for industrial applications.
