IMC Hall for current sensing Melexis

With its strong magnetic gain the biggest IMC LF is ideally suited for applications with low currents requiring high magnetic sensitivities up to 700mV/mT At the other end of the spectrum the smallest IMC XHF can linearly sense strong magnetic fields up to ±90mT for current sensing applications with very high power densities

Development of a mode tuning magnetic concentrator type

·The magnetic concentrator in Fig 2 b was defined as magnetic concentrator B MC B and the center distance was 10 mm The bottom surface of the permanent magnet adhered to the top surface of the magnetic concentrator and completely coincided and the magnetic was placed on the coil Fig 3 show top view of double layer variable pitch

Design of planar magnetic concentrators for high sensitivity

·The magnetic flux concentrators are usually made of high permeability μ r >10 000 amorphous alloys with low coercive field H c <1 A/m It has been already shown in literature [4] that the maximum amplification is achieved when the gap distance is equal to the concentrator s thickness and is increasing with the increase of the concentrator s length
