WCS1800 Hall Current Sensor

The unique package provides easy implementation without breaking the original system and makes current sensing possible.

The WCS1800 consists of a precise, low-temperature drift linear hall sensor IC with a temperature compensation circuit and a diameter of 9.0mm through the hole. Users can use the system’s electric wire by passing it through this hole to measure the passing current. This design allows system designers to monitor any current path without breaking or changing the original system layout at all. Any current flowing through this hole will generate a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage.
