The outbreak of COVID-19 virus is currently suppressing research and development activities in the electronics and semiconductor industries, and leading to the closure of multiple manufacturing plants worldwide. Due to supply chain disruptions, access to raw materials and components has been hinderedResearch on DC Current SensorAnd the production capacity of the manufacturer. In addition, the decline in consumer purchasing power and the decrease in the use of electric vehicles will further hinder market growth. However, the impact of COVID-19 will drive the development of autonomous technologies such as industrial robots and autonomous electric vehicles, accelerating market growth in the coming years. Hall effect current sensors hold over 45% of the market share and are expected to grow by approximately 6% during the forecast period. This growth is mainly attributed to the continuous development of Hall current sensors, such as chipless technology. This helps sensor manufacturers reduce bill of materials (BOM) and design dimensions, increasing their integration in several vertical industries.

Hall effect technology also has the advantages of high accuracy, good linearity, wide bandwidth, and low power consumption. Industry leaders are focusing on BiCMOS structures and current isolation based technologies to promote the advancement of Hall effect technology. Intelligent programmable Hall effect sensors are applied in industrial robots, traction motor inverters, intelligent batteries, and intelligent fuse devices. The continuous development of coreless sensors and the demand for programmable sensors in industrial automation will drive the application of Hall effect technology in the market.

In 2019, the closed-loop current sensor market accounted for over 60% of revenue share, and it is expected to have a compound annual growth rate of over 6% by 2026. These sensors provide high precision, low temperature drift, and fast response time in some industrial and commercial applications. These sensors can easily convert their output into voltage, thereby increasing their integration in the telecommunications sector to achieve high bandwidth and network infrastructure development.

The emerging development of 5G technology in the United States and other developed countries will bring about infrastructure deployment ranging from servers, base stations, distributed antenna systems to UPS, SMPS, and telecommunications power supplies. This will drive the market for closed-loop current sensors in the near future.

Due to the linear flow of current in circuits and servers, closed-loop sensor components are becoming increasingly popular in the telecommunications industry. These sensors are widely used in base stations for uninterruptible power supplies (UPS) and switch mode power supplies (SMPS) to measure alternating current (AC), direct current (DC), and pulse currents. In addition, closed-loop sensors are immune to electrical noise, providing stable current flow for electrical systems such as at distribution units (PDU), computer room air conditioning (CRAC), and power supplies, further driving market growth.
