            HAIS Series Industrial Current Sensors
                    The LEM HAIS series offers compact Hall effect current sensors that deliver accurate measurements for industrial applications
    

The LEM HAIS series offers precise measurement of DC, AC, and pulse currents from 50 A_RMS to 400 A_RMS, while ensuring galvanic isolation for enhanced safety and performance. Designed with a compact footprint for PCB mounting, the series includes five models that either feature an aperture for the primary conductor or integrate it directly, depending on the amperage requirements.

Operating reliably across a wide temperature range of -40°C to +85°C, HAIS sensors run on a single +5 V supply with reference access. Compared to standard HAIS-P parts, the HAIS-TP versions incorporate a solderable primary busbar for streamlined PCB integration. Leveraging open-loop Hall effect technology, these sensors deliver voltage output with fixed offset and gain, making them a dependable solution for accurate current measurement in demanding industrial applications.
