Alps Alpine at PCIM 2025

Current sensor ICs and integrated modules

Alps Alpine has effectively leveraged the know-how and technology acquired from developing various types of sensors to bring current sensors for battery-powered electric vehicles (BEVs) to market. By using innovative magneto-resistive technology, it is possible to measure current without using a magnetic flux concentrator, which is required in other designs. The result is a compact product that increases design freedom when integrated into traction inverters or the battery of an electric vehicle and improves energy efficiency, thus contributing to decarbonisation.

Magnetic sensor ICs

Magnetic sensors are devices that detect the size, direction and degree of change in the magnetism and geomagnetism that is emitted by magnets and currents and convert that into electrical signals. The small-sized magnetic sensors from Alps Alpine are made using the proprietary technology that the company has developed across many years of experience and are at use in a wide range of applications such as in contactless switches, as well as angle and direction detection.

DC-DC contactor relay

The new DC-DC contactor relay is designed for high-speed self-shutoff from the battery. It was specifically developed for electric vehicles (EVs).

This is part of a new concept currently being explored at Alps Alpine, aimed at contributing to the development of safe and functional systems for next-generation mobility.
