Introduction

The FHS AH current sensor is LEM new SMD open loop current sensor based on the Hall effect principle. It benefits from improvement in sensitivity and accuracy temperature stress compensation. It is suitable for DC, AC, pulsed and mixed current measurements. This field sensor has built in Integrated Magnetic Circuit (IMC), that gives an optimum sensitivity, to offer flexibility in compact design without requiring external magnetic core concentrator. It is a perfect solution to measure current flowing in a conductor such as a PCB track. High isolation between the primary circuit and transducer electronics can be obtained with a double-sided PCB.
