HAIS – Industry Current Sensors
The HAIS product series is tailored for measuring DC, AC, and pulse currents with nominal values ranging from 50 to 400 ARMS, while providing galvanic isolation.
Featuring a compact and distinctive design, HAIS current sensors are intended for PCB mounting. With 5 available models, HAIS sensors incorporate an aperture for the primary conductor or integrate it for select models with varying amperage.
Operating within a temperature range of -40 to +85°C, they are equipped with a single +5 V supply and offer reference access.
Compared to standard HAIS-P parts, HAIS-TP versions integrate a primary busbar designed to be soldered on PCB.
Additionally, HAIS sensors provide voltage output, fixed offset, and gain, utilizing the open-loop Hall effect technology to ensure reliable and accurate current measurements in industrial applications.
