TDK Product Features
TDK leverages its strengths as the world's first manufacturer to commercialize ferrite in order to develop ferrite with the optimal performance for use in products. The clamp alternating current sensor was developed to make maximum use of those characteristics. In conjunction with the expansion of the market for energy management systems for Industry 4.0, TDK has created a lineup of AC current sensors compatible with 30A to 600A to meet the need for high current support. These products are one-touch type clamps, which means they are easily attached to existing electric power equipment. The CUR 423x is a single-axis contactless magnetic-field sensor for galvanically isolated DC and AC current measurements. The Tunnel Magneto Resistance (TMR) sensing technology enables current measurements with high sensitivity and high accuracy in applications like battery monitoring systems of hybrid and electric vehicles (xEV).
