Magbase for high accuracy positioning - ASA ELECTRONICS INDUSTRY CO.,LTD

As shown in the figure, “Magbase” is an array of 3 magnets disposed on an iron plate with each polarity alternated（patented）.
By using “Magbase” instead of “Mag”, the effect of gap change on the sensing area can be minimized. As the arrayed magnets make the magnetic gradient neighboring the boundary of the sensing area dense, “Magbase” is capable of an extraordinary precise repeatability of the operating point compared to “Mag”.

■Magnetic Property

The distribution of the magnetic force of “Magbase” was measured under the conditions described. The figures are not guaranteed values but average values.
