How NOVOSENSE Is Building a Global Magnetic-Sensor Platform

NOVOSENSE is emerging as a high-volume magnetic-sensor supplier, but its clearest competitive position is measured in shipments rather than revenue. Industry reporting based on Yole data places the company fourth globally by magnetic-sensor shipment volume and first among Chinese suppliers; it reportedly shipped more than 1 billion magnetic sensors in 2025 and has surpassed 2 billion cumulative shipments. 64647

That growth sits within a broader analog and mixed-signal business. NOVOSENSE’s total revenue rose from RMB1.960 billion in 2024 to RMB3.368 billion in 2025, an increase of 71.8%. Those figures cover the company as a whole and should not be treated as magnetic-sensor revenue alone. 28

What the MagnTek acquisition changed

NOVOSENSE completed the acquisition of 100% of MagnTek in October 2024. MagnTek contributed RMB73.187 million in revenue and RMB3.979 million in net profit between the acquisition date and December 31, 2024. 7

Strategically, the deal broadened NOVOSENSE’s magnetic-sensing coverage. NOVOSENSE already had capabilities in analog, isolation, power and signal-chain products, while MagnTek brought additional magnetic-sensor technologies and products, particularly in areas such as angle and position sensing. Together, the portfolios cover current, switching, angle, position and speed applications. 61420

The acquisition also created the possibility of cross-selling and a full-year consolidation effect in 2025. However, the available disclosures do not separate MagnTek’s 2025 revenue from NOVOSENSE’s other sensor revenue or provide a quantified acquisition-synergy figure. The company-wide RMB1.408 billion year-on-year revenue increase therefore cannot be attributed to MagnTek alone. 278

NOVOSENSE’s magnetic-sensing technology stack

NOVOSENSE’s portfolio is built around multiple sensing platforms rather than a single technology. That gives designers more ways to balance sensitivity, precision, isolation, package requirements and cost.

• Hall-effect sensing: Hall devices support current measurement, switching, angle detection and position sensing. The company’s portfolio includes planar-Hall products and Hall-based angle encoders. 202733
• xMR sensing: The xMR category includes anisotropic magnetoresistance (AMR) and tunnel magnetoresistance (TMR). NOVOSENSE’s product materials identify AMR angle-encoder technology and TMR switches and latches. 2526
• Inductive and fluxgate sensing: These are complementary contactless approaches for position, angle, current and magnetic-field measurement within the broader portfolio described by the company and industry coverage. 20
• Flux-concentrator approaches: Flux concentrators can be used with magnetic-sensing structures to shape or strengthen the field reaching the sensing element. NOVOSENSE also describes work on higher-sensitivity current-sensing approaches, including gallium-arsenide Hall technology. 620
• Signal conditioning and calibration: Signal-conditioning ASICs connect the sensing element to the wider system by handling functions such as amplification, signal processing, interfacing and configuration. NOVOSENSE’s product materials also describe programmable magnetic-sensor signal-conditioning devices and calibration functions for selected products. 242529

The six product families and where they fit

1. Current sensors

Current sensors convert the magnetic field generated by current flow into a usable electrical output, often while maintaining galvanic isolation. NOVOSENSE positions its products for isolated-current measurement in applications including photovoltaic systems, power supplies, industrial inverters and electric-vehicle power electronics. Its NSM201x family is described for isolated measurement of currents below 200 A, with applications including OBCs, DC-DC converters, charging equipment and PTC heaters. 233336

In vehicles, these products can monitor current in battery, motor and electronic-control systems. The relevant design challenge becomes more demanding as platforms move from conventional low-voltage rails toward higher-voltage EV architectures, where isolation, response time and reliability are important system requirements. 223236

2. Switches and latches

Hall and TMR switches and latches provide contactless digital detection of magnetic presence, position or movement. Typical uses include actuators, doors, seats, pumps, valves, motors and appliance mechanisms. NOVOSENSE’s Hall switch families include unipolar, omnipolar and latch configurations, while its NSM105x family uses TMR for contactless position measurement. 2637

The appeal is mechanical simplicity: a magnet and sensor can detect movement without the physical wear associated with a conventional contact. Product specifications cited for selected Hall and TMR families cover industrial temperature operation from -40°C to 125°C. 1726

3. Angle encoders

Angle encoders translate the changing magnetic field around a rotating magnet into angular position. They can be used in motor control, valves, actuators, steering mechanisms, gimbals, joysticks and other rotary interfaces. NOVOSENSE’s NSM301x is a Hall-based contactless angle-sensor family designed for rotary position measurement, with applications including valve rotation, accelerator pedals and industrial steering systems. 273538

MagnTek’s AMR expertise adds another route for angle measurement. Its MT6826S, identified in NOVOSENSE’s product guide, uses AMR Wheatstone bridges arranged for high-speed and high-precision angle encoding. 25

4. Linear-position sensors

Linear-position sensors detect displacement or travel rather than rotation. In automotive and industrial systems, that can mean tracking the position of a seat, valve, actuator or machine mechanism. A contactless magnet-and-sensor arrangement can reduce dependence on wear-prone mechanical contacts. NOVOSENSE lists linear-position sensing among its magnetic-sensor products and applications. 2027

5. Speed sensors

Speed sensors detect rotational movement and, depending on the design, can also provide direction or commutation information. Their potential applications include motors, transmission components, industrial automation and vehicle systems. NOVOSENSE identifies speed sensing as one of its core magnetic product categories and links magnetic sensing to automotive motor and powertrain applications. 202227

6. Signal-conditioning chips

A sensing element is only one part of a measurement chain. Signal-conditioning chips process the raw output and provide the interface required by a controller or system. Depending on the product, this can involve amplification, compensation, conversion, configuration or analog and digital output handling.

NOVOSENSE’s portfolio includes magnetic-sensor signal-conditioning ASICs as well as signal-conditioning products for other sensor types, supporting its broader positioning as an analog and mixed-signal supplier. 18212729

Why automotive is a major application area

Automotive electronics bring together several of NOVOSENSE’s target use cases. In electric vehicles, magnetic current sensors can be used around batteries, motors, electronic controls, OBCs and DC-DC converters. Magnetic angle sensors can monitor motors, valves and actuators, while switches, latches and position sensors support body electronics and mechanical movement. 223236

Automotive designs generally place greater emphasis on isolation, temperature range, electromagnetic robustness, functional safety and long operating life than many consumer applications. NOVOSENSE has highlighted automotive-qualified products, including Hall switches for actuator position detection and magnetic products for electric-vehicle systems. 162237

Industrial and consumer applications

Industrial applications emphasize reliable sensing in motor drives, automation, robotics, inverters, power supplies and renewable-energy equipment. The same technology families can be adapted to detect current, rotation, position or speed in machines and power-conversion systems. 202228

Consumer products tend to prioritize compact packages, low power and cost efficiency. Contactless magnetic sensing can support interfaces and mechanisms such as gimbals, joysticks, rotary controls, watches and wearables, although the exact fit depends on the required accuracy, field environment and product design. 202734

The strategic takeaway

NOVOSENSE’s magnetic-sensor strategy is less about winning a revenue-share comparison with established global vendors and more about building scale, technology breadth and application coverage. Its reported fourth-place global shipment ranking shows significant volume, while the MagnTek acquisition helps fill gaps between current, switching, angle, position and speed sensing. 64647

The key caveat is measurement: shipment rankings, total company revenue and sensor-product revenue describe different things. Public information supports the view that NOVOSENSE expanded its platform and benefited from MagnTek’s integration, but it does not yet provide a clean, acquisition-specific measure of 2025 synergy. The strongest evidence is therefore the combination of rising shipment scale, a broader multi-technology portfolio and deeper coverage of automotive, industrial and consumer design requirements.
