TDK invests in 2X increased production capacity for TMR magnetic sensors
- The new investment will significantly increase production capacity of TDK’s TMR magnetic sensors in response to growing demand from automotive, consumer and industrial sectors
- The resulting expansion of production volume will increase the output of sensor units by approx. 2X
April 27, 2023
TDK Corporation (TSE: 6762) has announced that it will increase the production capacity at its TDK Asama Techno Factory (Saku-shi, Nagano, Japan) to strengthen its TMR magnetic sensor production system in response to increasing demand. The production volume after this investment will be approximately 2 times the current monthly production from the first half of 2025.
TDK’s TMR magnetic sensors, leveraging the company’s magnetic and thin-film technology expertise developed over many years, boast high precision, high reliability and excellent temperature characteristics, and enable stable operation. For this reason, they have become the preferred sensors used by the automotive industry in applications that require precision, reliability and safety, such as angle sensors for assist motor control and brake booster motor control in electric power steering (EPS), current sensors for battery charge/discharge control, etc. Additionally, the sensors are also widely used in robots, smartphones, and other consumer products because of their lower-power consumption. Demand is growing for angle sensors and current sensors for automotive applications, while industrial equipment manufacturers have demonstrated similar activity.
The TDK Asama Techno Factory has historically been an important center utilizing the cutting-edge magnetic technology that represents TDK’s heritage. It was previously a manufacturing center for wafers for HDD magnetic heads, undergoing a significant business portfolio transformation in 2014 to achieve the successful commercialization of TMR magnetic sensors for automotive and other applications.
Against the backdrop of medium-to-long term increasing demand from multiple market sectors, TDK’s current move to aggressively increase its production capacity at the Asama Techno Factory will enable it to increase its value to global customers and partners looking to utilize TDK TMR magnetic sensor technology in current products and new applications.
- TMR: Tunnel Magneto-Resistance. Of all magnetic field sensors, TMR offers the greatest sensitivity.
