Introduction  

        Vinbelltech’s  ACM20A miniature, open-loop current sensors incorporate our AH69X  Series miniature ratiometric linear Hall-effect sensor. The sensing element is encapsulated in a printed circuit board-mountable plastic package. The combination of sensor, flux collector and housing comprises the current sensor assembly. These sensors are ratiometric output.
