MLX90423 - Long Stroke Linear Application Application note
■This application note provides a step-by-step guideline to start a long stroke, usually longer than +/- 15mm1, linear application with stray-field immunity design in combination with main stream Triaxis® sensors MLX90423.
■This design of the magnetic angle measurement system is based on the needs of the particular application, such as the available airgap, accuracy requirements, temperature range and properties of the Triaxis® Hall sensor.
■A thorough understanding of the Triaxis® Linear Legacy sensing and Linear Stray-field Immune (SFI) sensing is required to continue reading this document.
●Conclusion: The 3 methodologies mentioned above provide a starting point of stray-field immune long stroke design. Below we list again the typical magnet length vs stroke length and essential characteristics per design, com- pared to the reference Linear Legacy 2-pole and Linear SFI design.
