Electronic Compass

The World's Smallest Class

Asahi Kasei Microdevices (AKM) is a leading manufacturer of 3-axis electronic compass using Hall element technology. We have the leading market share in the global 3-axis electronic compass for consumer applications and play a pivotal role in expanding the use of the electronic compass.

AKM electronic compass uses magnetic sensors (Hall element) with wide dynamic range and ideal linearity. The silicon monolithic structure achieves high accuracy and reliability, and it is optimized for high-volume manufacturing. Based on this technology, AKM's electronic compass can detect azimuth direction with a very high accuracy. In addition, with small and thin packaging, AKM’s electronic compass is widely used in products with limited mounting space, such as Smartphones. 
AKM, with its extensive knowledge of electronic compass, is the ideal partner if you are considering to implement a “pedestrian navigation with GPS” on a cell phone, mobile tablet or mobile PC. 

We provide not only hardware, but also DOE™ compensation software (winning "the Imperial Invention Award of the Japan Institute of Invention and Innovation" FY 2012), in addition to other software applications that enhance the user experience with our electronic compass.
The combination of hardware, software and technical support is an advantageous characteristic of the AKM electronic compass.

We will continue to provide the best solution through development of the compact, low-voltage and high-performance electronic compass and advanced software to our customers in the future.
