Market Synopsis

The Global Current Sensor Market was valued at USD 2.12 billion in 2017; it is expected to reach USD 3.71 billion by the end of the forecast period growing at a CAGR of 8.3%.

Current sensors are used to sense alternating current (AC) and/or direct current (DC) within a circuit, by clamping the sensor around the wire. Current sensors are segregated as either closed loop or open loop sensors. Current sensors are mainly available for alternating current sensing and direct current sensing with output detection ranging from a few milli-amperes to a thousand amperes. Both open-loop and closed-loop sensors are used to measure AC and DC and provide isolation between the output of the sensor and the circuit being measured. Open-loop current sensors are preferred in most battery-powered applications, due to their low operating power requirement. Most current sensors use Hall effect and magnetoresistive principles as these sensors have different characteristics for performing different applications.

Current sensors are widely used in servo motor drives, static converters for DC motors, battery and UPS devices, and power supplies. The major factor contributing to the growth of the current sensor market is the rising need for current measurement in industrial applications for motor current sensing, robotics, and solar inverters. In addition, increased use of fully integrated and programmable current sensors in consumer electronics and automotive industries is expected to contribute to the market growth.
