1. Type Segment: Hall Effect Current Sensors
Hall effect current sensors are widely used in automotive and industrial applications to measure DC and AC currents. These sensors are based on the principle of the Hall effect, which involves the production of a voltage across an electrical conductor when a magnetic field is applied perpendicular to the current flow. Hall effect current sensors offer high accuracy, low power consumption, and galvanic isolation, making them suitable for high-performance and safety-critical applications. The growing demand for electric vehicles and the increasing focus on energy efficiency in industrial processes are driving the adoption of Hall effect current sensors.
2. End-User Segment: Automotive
Current sensors play a crucial role in modern automotive systems, where they are used for battery management, motor control, power steering, and other key functions. In the automotive segment, current sensors are integrated into electric and hybrid vehicles to accurately measure the flow of electrical current in traction motors, battery packs, and charging systems. With the rising demand for electric vehicles and the development of advanced driver assistance systems (ADAS), the automotive industry is expected to be a significant market for current sensors.
