PRODUCTS
Asahi Kasei Microdevices (AKM), the Hall element leader, has developed advanced current sensors "Currentier" using the high-sensitivity compound semiconductor technology it has cultivated through its Hall elements, combined with Asahi Kasei Microdevices' advanced package design and analog circuit design technologies.
The name "Currentier" was made by combining "Current" and "Frontier". We named our product Currentier because it is a leading product in the field of current sensors thanks to its superb performance.
"Currentier" is magnetic open-type current sensor with a built-in high-sensitivity Hall element. They can detect both DC and AC currents quickly and with a high degree of accuracy. Despite their small size, they generate less heat and have 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, helping solve your problems.
What makes AKM different ?
Features of Currentier
- Low heat generation
- Wide current detection range
- High speed
- High isolation
- High resolution and high accuracy
Solutions
Currentier can contribute to solving various problems of control equipment with the above features.
Basic knowledge of current detection
Currentiers are classified as coreless current sensors, which is one of the current sensing methods. Other current detection methods include shunt resistor + insulated amplifier/insulated ADC and cored current sensors.
In the "Tutorials" section we explain the advantages and disadvantages of each detection method in detail. This section also provides information to help you select the right current sensor for your application and useful information that can help you solve your current detection problems.
