The global current sensor market size was valued at USD 1,822 million in 2021, envisioned to reach USD 3,239 million, expanding at a CAGR of 6.6% during the forecast period. Current sensors are devices that use a magnetic field for sensing the current and giving a proportional output. They are also known as current transformers or CTs. Current sensors measure the amount of current that is flowing through a wire. They can operate on both AC and DC currents. A current sensor is a device that can detect current and convert it into an easily quantifiable output voltage. This voltage is proportional to the amount of current flowing through the path that is being measured. There is a vast selection of sensors, each suited for a particular current range and ambient condition. They are utilized in several applications, including motor driving circuits and inverter circuits. Automotive, consumer electronics, and telecommunication industries use current sensors.
Increased power management systems in data centers to improve efficiency and speed while reducing power consumption drives the market growth. Integrated current sensors with backup power systems like inverters and UPS systems enable battery protection during the charging stage and provide efficiency, increasing demand in data centers. In addition, stringent government regulation regarding the management of data center power usage is one of the primary factors influencing the growth of the present sensor industry. However, technological challenges and high prices connected with current sensors globally impede the expansion of the market. In contrast, the increasing adoption of 5G technology raises the demand for closed-loop current sensors, which is anticipated to generate attractive prospects for the current sensor market.
