Alps Alpine begins mass production of high-precision, high-efficiency magnetic angle sensors for automotive engines

Alps Alpine Co., Ltd. (TSE: 6770; Chairman and CEO: Toshihiro Kuriyama) has added two new products to its line of magnetic sensors to support the continued electrification of vehicles. This builds on experience gained in the automotive market in the areas of steering angle sensing and electronic throttles.

Designing for redundancy is increasingly a requirement for automotive driving systems as the world seeks to embrace driver assistance and autonomous vehicles. Using multiple sensors was once the typical way to achieve redundancy, to ensure that systems operate safely even in the event of a failure. In recent years, however, smaller systems more often mean fewer parts and therefore greater demand for angle sensors that provide redundancy by providing two output signals from a single product. alpine alps the new magnetic pickups have a built-in amp to support downsizing and meet redundancy design needs with an unbalanced high output of 3Vpp. The dual matrix model1 meets the requirements of a full redundant design and can be supplied as a single product. Considered for use in automotive engines, magnetic pickups can be used to create conditions resistant to outside magnetic disturbances. This is because they perform well in high temperature environments up to 150 degrees C while achieving strong magnetic field resistance of 120mT thanks to the application of the original thin film technology.

Magnetic sensors are being mass produced with applications envisaged in automotive engines and 15 million units are expected to be sold by 2030. alpine alps will also continue the development of smaller and inexpensive magnetic sensors resistant to external magnetic disturbances.

alpine alps develops and manufactures sensors for a wide range of applications in consumer products such as smartphones to automotive electronics. Seeking to contribute to society through our business, we will continue to strive to develop products that best meet customer and market needs.
