Current Sensor Global Market Report 2025

A current sensor is a device designed to detect electric current and convert it into an output voltage that can be easily measured, proportionate to the current flowing through the measured circuit. Current sensors serve various purposes, including power metering, measuring current supply, diagnosing control systems, and managing loads from motors.

The major types of current sensors include closed-loop and open-loop. Closed-loop current sensors feature a ferroelectric core with a sensing element (or field probe) placed in a gap in the core. Technologies employed in current sensors include hall effect, shunt, fluxgate, and magneto-resistive. These sensors find applications in diverse fields, such as motor drives, converters and inverters, battery management, UPS and SMPS, starters and generators, grid infrastructure, and more. They are utilized by various end-users, including automotive, consumer electronics, industrial, telecommunication, and others.

The rising demand for electric vehicles (EVs) is anticipated to significantly boost the growth of the current sensor market in the future. An electric vehicle is defined as a car powered by a battery, which can be charged from an external source. Current sensors are essential in automobiles for managing the motor drive, controlling the direct current conversion of the motor's regenerative current, and detecting the charged and discharged currents of the batteries in electric and hybrid vehicles. As a result, the increasing demand for electric vehicles is expected to enhance the current sensor market. For example, in July 2023, the International Energy Agency, a France-based intergovernmental organization, reported that electric vehicle sales reached 10 million in 2022 and are projected to rise to 14 million in 2023. Consequently, the growing demand for electric vehicles is driving the expansion of the current sensor market.

The rapid proliferation of electronic devices, particularly smartphones, is expected to further propel the growth of the current sensor market. Smartphones are handheld electronic devices equipped with touchscreen displays, built-in operating systems, and various software applications. In smartphones, current sensors play a vital role in monitoring and controlling charging, battery management, power consumption, and component operations to optimize performance and safety. For instance, in February 2023, Uswitch Limited, a UK-based financial conduct authority, noted that as of 2022, there were 71.8 million mobile connections in the UK, reflecting a 3.8% (approximately 2.6 million) increase compared to 2021. The UK population is projected to grow to 68.3 million by 2025, with an estimated 95% (around 65 million individuals) expected to own a smartphone. Thus, the proliferation of electronic devices, including smartphones, will drive the growth of the current sensor market.

Major players in the current sensor market are advancing technology with innovations such as coreless high-current sensors, aimed at improving accuracy, reducing size, and enhancing efficiency in power monitoring and control applications. Coreless high-current sensors are sophisticated current sensing devices that measure high electrical currents without relying on a magnetic core, which is commonly found in traditional current sensors. For example, in May 2024, LEM, a France-based designer and manufacturer of measurement and control instruments primarily for the aeronautics and space sectors, introduced the LEM HTFS 600-S and HASS 1000-S. These two notable coreless high-current sensors are engineered for precise measurements in industrial settings. The HTFS 600-S can measure currents up to 600 A, providing high linearity and rapid response times, making it ideal for monitoring transient currents. In contrast, the HASS 1000-S accommodates measurements up to 1000 A, featuring a compact design that facilitates its integration into systems such as electric vehicles and renewable energy setups.

Prominent entities within the current sensor market are directing their efforts toward the development of advanced products, notably focusing on automotive-qualified integrated current sensors, in a bid to gain a competitive edge. These specialized sensors, designed and certified to adhere to rigorous reliability and performance standards tailored for automotive applications, offer precise electrical current measurement within vehicles without necessitating external isolation components. A case in point is Novosense AB's launch of the NSM2019 in June 2023-a high-performance automotive-qualified integrated current sensor featuring low impedance and high isolation. This chip, renowned for its fully integrated solution, eliminates the requirement for external isolation components, catering to precise current measurement needs in automotive and industrial systems. Boasting a distinctive package design, the NSM2019 achieves an industry-leading primary conductor resistance of merely 0.27 mΩ and supports continuous currents up to 100 A. This innovation addresses heat dissipation challenges within compact systems. Offered in both automotive-qualified and industry-qualified variants, the automotive-qualified version adheres to stringent AEC-Q100 Grade 0 reliability standards, operating flawlessly in harsh environments spanning from -40 to 150 °C. It further provides rapid overcurrent protection with an impressive response time of 1.5 μs, with an adjustable default overcurrent protection threshold ranging from 75% to 175% of full-scale current.
