In summary, Asahi Kasei Microdevices (AKM) has developed Currentier™ advanced current sensors using the high-sensitivity compound semiconductor technology it has cultivated through its Hall elements, combined with an advanced package design and analog circuit design technologies. Currentier is a magnetic open-type current sensor with a built-in high-sensitivity Hall element. It can detect both DC and AC currents quickly and with a high degree of accuracy. Despite its small size, it generates less heat and has high isolation. Currentiers are safe, high-performance products that are available in many models, and which can be used for current detection in a variety of applications.
