This type of large deal will increase the demand for current sensors in the single phase and drive suppliers to add digital services and increase the lifespan of their products.

Demand will develop into two separate tiers over the next three to five years. Volumes of meters and appliances will remain price sensitive. Volumes of electric vehicles and EV charging, battery storage, building automation, and industrial controls will require accuracy, isolation, and software support. Suppliers with design wins will have ample application engineering and reliable capacity. Vendors who are solely catalog focused will struggle as qualification requirements grow.

Strategic Growth Opportunities in the Single-Phase Current Sensor Sale Market

From 2024 to 2026, electrification, distributed energy, factory automation, and increased safety regulations will create demand for single-phase current sensor sales. According to Lucintel, most current sales are replacements. However, Lucintel has identified opportunities where current sensors and monitoring software or other technologies reduce installation costs. Instead of selling in bulk, suppliers must design sensors for specific applications, ensure better certifications, and offer regional services.

• EV Charging & Residential Energy Management: Due to their small size, current sensors can be used in wallbox load protection and balancing, as well as in home energy controllers. In March 2025, the International Energy Agency (IEA) reported approximately 17 million electric vehicles were sold worldwide in 2024 for the first time. Demand for this application is expected to increase as households manage charging with solar energy generation and dynamic utility rates.
• Smart Building Retrofit: Legacy distribution panels can be made monitored assets with little to no rewiring using clip-on current sensors. In January 2025, the U.S. Department of Energy indicated that in the U.S., buildings account for approximately 40% of energy consumption. The retrofit of smart buildings will increase as building owners demand energy efficient retrofits without large capital expenditures.
• Higher-value Medical and Laboratory Equipment: Isolated sensors with low noise can be used with impedance and patient support systems that require continual operation of sample and accessory control to not disrupt system operation. In February 2025, the World Health Organization (WHO) stated that there was a shortage of 4.5 million health care workers. Equipment manufacturers will elect to use compact sensor technologies that improve equipment uptime and simplify compliance.
• Onsite Automation Production and Engineering: Machine automators deal with lengthy qualification processes due to the need for site visits. It was reported that in 2023, 542,000 industrial robots were built and installed worldwide (International Federation of Robotics, April 2025). The need for industrial automation will drive the need for sensors customized to specific control cabinets and voltage types. This will create business opportunities for sensor manufacturers.
• Sell Position Sensors for Aftermarket Services: Sensors installed on equipment during an initial install can provide the end user with aftermarket services such as remote diagnostics, calibration, and replacement. In 2025, the U.S Energy Information Administration reported that by 2028 data center electricity demand will more than double. More sensor sales will be made in aftermarket service contracts as customers will pay to better monitor the condition of their assets.

The demand for more accurate sensors will increase along with the demand for sensors that are easier to install and that include diagnostics and isolation. It is expected that companies that manufacture sensors with these features will capture a large portion of the market. In the commoditization channels, as expected, pricing will be competitive, but the introduction of services that have recurring revenue, such as calibration, replacement, and fleet analytics, will enable profitability due to reliable supply and appreciable savings in energy consumption.

Single-Phase Current Sensor Sale Market Drivers and Challenges

The single-phase current sensor sale market is influenced by factors such as technology, economics, regulations, and sustainability. Increased demand is driven by the need for power monitoring in residential, commercial, renewable, and electric vehicles as well as appliances. According to Lucintel, the market will continue to grow due to the price of sensors, the ability to manufacture sensors, the modernization of the power grid, and the ability to digitally control and adapt systems to the modern power grid. However, market growth is limited by challenges of transition of technology, supply chain reliability, the risk of cyber attacks, and the uniformity of regulations. Opportunities will favor suppliers that are capable of integrating the best overall combination of price, size, accuracy, and wireless communication in the next few years.

The key elements that help define and drive the market for single-phase current sensors are:

• Customer Demand: The increase in the number of smart homes, connected energy resources, energy management systems, and electric vehicle chargers will increase the demand for compact current sensors. The International Energy Agency (June 2025) showed that they expect annual growth of 4% of global electricity demand from 2025 to 2027. In the next 3 to 5 years, there will be an increase in the use of current sensors to reduce energy costs, identify unusually high energy consumption, and optimally manage flexible loads. This will create a constant need for retrofit sensors, smart meters, and monitoring systems that operate reliably and cost effectively in residential and light commercial markets.
• Technology Improvements: Innovations in Hall Effect, shunt-based, fluxgate, and magnetic sensing technologies allow for improvements in accuracy, isolation, miniaturization, and response speed. In 2025, product launches for power-monitoring systems will focus on measurement accuracy of 1% or better. It is expected that over the next 3-5 years, improvements in sensor fusion, edge processing, wireless connectivity and application-specific integrated circuits will allow for more sophisticated energy management. Also, power sensors will help reduce overall power consumption and will continue to enable improvements in ease of deployment of sensor systems. This decrease in system complexity and power consumption will stimulate the use of miniaturized sensors in new contexts like smart plugs, solar inverters, battery systems and smart appliances and industrial controllers.
• Regulatory Support: Energy efficiency acts, electrical safety acts, Modern Grid acts and Acts for the Energy Performance of Buildings help stimulate the installation of monitoring systems. The updated version of the Directive for the Energy Performance of Buildings went into effect throughout the EU member states in May 2024, with an emphasis on the measurement of energy used in buildings. It is expected that over the next 3-5 years, compliance Acts combined with these regulations will lead to the installation of current sensors in meters, charging systems, HVAC systems as well as other energy systems. Regulatory emphasis on traceability and efficiency will serve to benefit companies that offer such products.
• Sustainability: Currently, there is a growing focus on removing carbon from the economy. This has led to growth in areas such as solar generation, battery storage, heat pumps, appliances, and even systems to manage customer demand. The European Union renewable energy directive goal for at least 42.5 percent renewable energy by 2030 continues to drive the deployment of technologies in the 2025-2027 time frame. In a similar time span, there is a growing need for single-phase current sensors to measure self-consumption, identify energy loss, balance loads, and save carbon. Building more sustainably will lead to greater demand for energy optimization and monitoring within manufacturing and even low-power applications.
• Manufacturing Efficiency: Costs have decreased and consistency has improved with the increased use of automated assembly and integrated semiconductors and standardized sensor modules. By February 2025, industry automation began to focus on inline testing and digital quality control, resulting in decreased defects and shorter cycle times. For the next three to five years, high-volume appliances, chargers, smart meters, and consumer electronics will use current sensors, thanks to cost-effective mass production. This will be achieved through customized products and standardized modules. This will also allow the same supplier to have multiple production lines to meet different needs.

The challenges facing this market are:

• Supply Chain Instability: Current sensors rely on semiconductors, magnetic, and copper materials as well as specific packaging and manufacturing equipment. Revenues of the semiconductor industry were projected to exceed $600 billion in 2025 (January 2025). This illustrates a trade-off between a growing market and an increasing dependency on complex supply chains. In the next 3-5 years, geopolitical tensions will have an unknown, but likely negative, impact on logistics with increasing lead times and costs. Manufacturers will need numerous suppliers, planned regional production capacities, a strong material management strategy, and the ability to modify materials. This will enable them to maintain delivery assurance and customer trust.
• Technical Complexity: Calibration, control of electromagnetic interference, thermal interference, isolation and/or tensile design, and compatibility with communication protocols are all examples of challenges when integrating sensors with electrical systems. In 2025, many new monitoring systems began to move toward wireless and edge-connected architectures; however, installation and application integration varied. In the next 3-5 years, the variation in application will challenge smaller businesses and residential users unless products are simpler to configure. Suppliers must provide standardized interfaces, provide automation and support for tools and software, and design products with reliability at small form factors that can operate in harsh electrical conditions.

Current sensors are able to record detailed usage data about electricity and can send this information over the internet. In December 2024, the deadline for the first implementation of obligations will be December 2027. The compliance deadline makes it easier to plan for the Cyber Resilience Act for connected products of the European Union. The next three to five years will require manufacturers to spend more on secure firmware, authenticated products, and managing vulnerabilities. There might also be additional costs because of regional differences in certification systems that create barriers to selling products. Manufacturers that ignore cybersecurity and interoperability will be at risk for recalls, penalties from regulators, slower acceptance of products by consumers, and a damaged reputation.

The market for single-phase current sensors will grow because of an increase in demand for electricity, the deployment of more distributed energy, electrification, digital monitoring, and the requirement of greater efficiency. This market will grow due to improvement of technologies, automation of manufacturing, and regulations that support sustainability and will broaden the use for current sensors. The growth of current sensor market is also predicted to be lower due to challenges in integration, supply chain, and the requirement of cybersecurity. The current sensor market could also be dominated by companies if they focus on designs that are flexible and easy to install, supply is resilient in the region they are operating, and certified performance and secure connectivity. The market is expected to grow because current sensors are going to be used in almost every market to build decentralized, efficient, and connected systems in residential and commercial markets.
