The FHS AH field sensor is LEM's latest surface mount design (SMD) open-loop current sensor, relying on the Hall effect principle. It benefits from enhanced sensitivity and accurate temperature stress compensation. It can be used to measure DC, AC, pulsed, and mixed currents. This field sensor is equipped with an Integrated Magnetic Circuit (IMC) which optimizes sensitivity, allowing for a versatile and compact design that eliminates the need for an external magnetic core concentrator.
This sensor is an ideal choice to measure current flow within a conductor like a PCB track. Strong isolation between the primary circuit and transducer electronics can be achieved using a double-sided PCB, making it a highly effective solution.
