Segmental Insights
Type Analysis
Based on type, the segmentation includes hall-effect, flux gate current sensors, and XMR technologies. The hall-effect segment held the largest share in 2024. These sensors operate on the principle of the hall-effect, where a voltage difference is generated across a conductor when a magnetic field perpendicular to the current flow is applied. This characteristic makes them highly versatile for measuring both AC and DC without direct electrical contact, which enhances safety and minimizes power loss. Their widespread adoption is attributed to their reliability, cost-effectiveness, and established presence in diverse applications, particularly within the automotive sector for battery management systems and motor control, and in various industrial and consumer electronics products.
XMR (magnetoresistance) technologies segment is anticipated to grow at the highest growth rate during the forecast period. These advanced sensor types offer superior sensitivity, lower power consumption, and better immunity to stray magnetic fields compared to traditional Hall-Effect sensors. The rising demand for high-precision and compact current sensing solutions in emerging applications, such as advanced driver-assistance systems (ADAS), complex industrial automation, and highly integrated consumer electronics, is driving the rapid expansion of the XMR segment.
