NOVOSENSE × Yole Group: global magnetic sensor market set to reach USD 4.3 Billion — Exploring technology evolution and application opportunities

The global magnetic sensor market is expected to expand by approximately USD 1 billion over the next six years. According to Yole Group, the market is projected to grow from approximately USD 3.3 billion in 2025 to USD 4.3 billion in 2031, representing a compound annual growth rate of around 4.5%.

This expansion is about more than rising sensor demand. Automotive electrification, the transition of photovoltaic and energy storage systems toward higher-voltage platforms, and the rapid development of humanoid robots and smart devices are creating increasingly diverse requirements for accuracy, power consumption, bandwidth, mounting architecture, and reliability—opening up new technology choices and product opportunities.

NOVOSENSE and Yole Group recently co-hosted a media briefing on magnetic sensors. Yole Group shared its analysis of the global market, application trends, and technology evolution, while NOVOSENSE presented its broad sensor portfolio and diverse technology roadmap, demonstrating how tailored sensing solutions can address the needs of different industries. NOVOSENSE also introduced several new magnetic sensor products at the event.

According to Yole Group, the global magnetic sensor market was valued at approximately USD 3.3 billion in 2025 and is projected to reach around USD 4.3 billion by 2031, representing a compound annual growth rate of approximately 4.5%. Automotive and mobility represent the largest application market, while the industrial, consumer electronics, and medical sectors continue to generate new demand for sensing technologies.

According to Yole Group, NOVOSENSE ranks fourth globally in magnetic sensor unit shipments and first among Chinese suppliers. Cumulative shipments of the company’s magnetic sensor products have exceeded 2 billion pcs, with more than 1 billion pcs shipped in 2025 alone. These products are now widely used across automotive, industrial, consumer electronics, and other applications.

Behind this market growth lies the increasing diversification of application requirements. Automotive applications emphasize reliability, long-term stability, and performance in complex operating environments. Photovoltaic and energy storage systems require accuracy, bandwidth, and robust insulation for current sensing. Robotics applications must balance angle-sensing accuracy with mounting architecture, while smart devices place greater demands on power consumption, size, and integration.

Because sensing targets, system architectures, and operating environments vary significantly across applications, sensing technologies are not simply substitutes for one another. Technology selection must be based on balance performance, cost, mechanical structure, and reliability according to the specific requirements of each application.

Building on its in-depth understanding of application systems, NOVOSENSE has established a multi-technology portfolio encompassing Hall-effect, AMR, TMR, inductive, and fluxgate sensing technologies. The company has also developed six major product families: current sensors, magnetic switches and latches, angle encoders, linear position sensors, speed sensors, and ASICs.

Automotive is the world’s largest application market for magnetic sensors and has long been a strategic application of NOVOSENSE. As vehicles become increasingly electrified and electronically controlled, magnetic sensors are being widely adopted across body electronics, thermal management, powertrain, and chassis systems, while continuing to expand into more critical sensing functions.

To address the sensing requirements of different automotive systems, NOVOSENSE has developed a magnetic sensor portfolio covering four major vehicle domains:

In electric vehicle traction systems, for example, motor inverters require fast and accurate high-current sensing within a limited installation space. To address this need, NOVOSENSE has introduced the NSM2025 linear current sensor. The device integrates a U-shaped magnetic concentrator and can be mounted directly on a PCB. It delivers overall accuracy of approximately 1.5% across the full temperature range, a bandwidth of up to 270 kHz, and a typical response time of 2 μs.

In photovoltaic, energy storage, EV charging, and uninterruptible power supply systems, current sensors support current measurement, control feedback, and system protection while meeting the corresponding electrical isolation requirements. In photovoltaic and energy storage systems, current sensing is required at multiple stages—from solar panels and MPPT boost converters to energy storage batteries and grid-tied inverters. However, each stage has different requirements for current range, accuracy, bandwidth, and isolation capability.

NOVOSENSE offers a broad portfolio of current sensors covering different current ranges and operating-voltage levels to address the requirements of these systems.

As photovoltaic systems migrate toward 1,100 VDC, 1,500 VDC, and even 2,000 V high-voltage platforms, insulation requirements are becoming increasingly stringent. NOVOSENSE has introduced the NSM2051 integrated current sensor to address this trend. Featuring an ultra-wide-body package, the device provides a creepage distance and clearance of 15 mm and supports a working voltage of up to 2,800 VDC for basic insulation. It offers high-voltage photovoltaic systems a current-sensing solution that combines robust insulation, high integration, and surface-mount assembly.

Robot joints and industrial servo systems rely on encoders to obtain angle and position information. As robot joints become smaller and increasingly adopt hollow-shaft designs, encoders must not only meet demanding accuracy requirements but also accommodate different mounting architectures and operating environments. Hollow joints, in particular, must reserve space along the central axis for cable routing, creating greater demand for off-axis sensing solutions.

To meet different mounting and performance requirements, NOVOSENSE has introduced Hall-effect, AMR, and inductive encoder products covering both on-axis and off-axis configurations.

Representative products include:

By combining different mounting configurations and sensing principles, NOVOSENSE can provide flexible angle-sensing options for robot joints, servo motors, and other industrial motion-control equipment based on joint architecture, accuracy, rotational speed, and operating-environment requirements.

Across gaming peripherals, smart wearables, and smart home devices, position sensing is evolving from simple on/off state detection toward multidimensional information such as direction, displacement, and angle. Joysticks, smartwatch crowns, and foldable-device mechanisms require multi-axis magnetic field measurement and angle calculation within highly constrained spaces. Meanwhile, applications requiring extended standby time—such as TWS earbud charging cases and door/window sensors—place greater emphasis on sensitivity and power consumption.

From automotive and energy systems to robotics and smart devices, different systems impose distinct requirements for accuracy, power consumption, bandwidth, insulation capability, and mounting architecture. A thorough understanding of application-specific sensing requirements is therefore fundamental to selecting the appropriate technology and defining the right product architecture.

Looking ahead, NOVOSENSE will continue to deepen its system- and application-level expertise in key markets, expand its multi-technology portfolio, and provide customers with a broader range of flexible and reliable sensing solutions.
