360 Degree Rotary Position Sensing with Novel Hall Effect Sensors

March 1, 2006 By: Vincent M. Hiligsmann, Melexis Sensors

A new breed of Hall sensors can sense all three magnetic flux density components at a single point.


The Triaxis Hall sensor MLX90316 promises to simplify the design of a noncontact rotary position sensor. Triaxis Hall technology offers a real alternative to inductive- and magnetoresistive-based technologies for replacing conventional resistive contacting potentiometers. It also enables so-called 1D (e.g., linear position sensor), 2D (e.g., rotary position sensor), and 3D (e.g., joystick position sensor) sensors.
