Düsseldorf, April 23, 2019 – Asahi Kasei Microdevices Corporation (AKM) presents itself at PCIM Europe – the world’s leading exhibition and conference for power electronics, intelligent motion, renewable energy as well as energy management – taking place from May 7-9 in Nuremberg, Germany. Sensor solutions for various applications constitute the focus of this year’s presentation.

With its first-time appearance at PCIM Europe, Asahi Kasei Microdevices, a subsidiary of the Japanese technology group Asahi Kasei, continues to strengthen its activities on the European market. With semiconductors and sensors, the company provides cutting-edge solutions to various industries ranging from home/building/factory automation to automotive. The product range includes current sensors with current ratings from 5A to 180A and response time of less than 1us. The company’s fast and accurate current sensors are key components in several power electronics systems.

Coreless Current Sensor

One highlight are the coreless current sensors of the “CZ370x” series, which comply with the product safety standard UL61800-5-1 and feature a current detection range from 5A to 180A. Next to the maximum effective current of 60arms and low primary conductor resistance, the series’ fast response time characteristics of less than 1us stand out. The stray magnetic field effect reduction ability and the fast response characteristics will be demonstrated at the booth, where visitors can convince themselves of the sensors’ performance.

With the “AK310x”, Asahi Kasei Microdevices also exhibits the newest addition to the coreless current sensor family, with the industry’s highest level of low-noise characteristics.

High Precision Rotation Angle Sensor

In addition, the company shows the “AK7454”, a high precision 14-bit rotation angle sensor. Compared with optical encoders, it has a high environmental resistance against dust and oil, which contributes to the efficiency of the assembly process. Additionally, a 0.1° angle error accuracy is accomplished with the company’s unique angle correction function when it is mounted on a motor unit. Visitors are invited to attend demonstrations of the high accuracy compensation with a corrected angular error.

3D Magnetic Sensor

Another highlight is a demonstration of the 3D magnetic sensor “AK09970N”. As the world-leading manufacturer of electronic compass ICs used in smartphones, Asahi Kasei Microdevices is increasing the scope of a new 3-axis magnetic sensing solution by taking advantage of the technology cultivated from the electronic compass. Based on the company’s compass technology, the measurement range of the “AK09970” is widely expanded to optimize the magnetic field detection of the magnet, which is suitable for security and controller applications.

Asahi Kasei Microdevices exhibits in Hall 7, Booth 539. In addition to this, Business Development Manager Takahiro Ezaki is giving a lecture on “The Next Generation Current Sensors” on Tuesday, May 7, from 2.20 to 2.40 p.m. (in the exhibitor forum, Hall 7).
