Application Examples Absolute Rotary Position Sensor Absolute Linear Position Sensor Non-Contacting Potentiometer 3. Description The MLX90340 is a monolithic sensor IC sensitive to the flux density applied orthogonally and parallel to the IC surface. The MLX90340 is sensitive to the three components of the flux density applied to the IC (i.e. Bx, By and Bz). This allows the MLX90340 with the correct magnetic circuit to decode the absolute position of any moving magnet (e.g. rotary position from 0 to 360 Degrees or linear displacement, stroke - Figure 2). It enables the design of novel generation of non-contacting REVISION 2-31AUG2020 3901090340 MUXMLX90340 Datasheet Contents 1111....
