Through Hole Current sensor WCS7700 Introduction

The WCS7700 consists of a precise, low-temperature drift linear hall sensor IC and 10.4×8 mm2 split through hole. Users can use system’s own electric wire by pass it through this hole to measure passing current. The unique spring structure of WCS7700 can improve the tightness on both sides of the iron core, making measurement more stable and reducing the influence of structural opening and closing tolerances.

This design allows system designers to monitor any current path without breaking or changing 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.

The Winson WCS7700 current sensor provides economical and precise solution for both DC and AC current sensing in industrial, commercial and communications systems.

The terminals of the conductive path are electrically isolated from the sensor leads. This allows the WCS7700 current sensor to be used in applications requiring electrical isolation without the use of opto-isolators or other costly isolation techniques and make system more competitive in cost.
