5 Conclusion

Contact-based position sensing solutions such as potentiometers have issues with wear and tear that reduce product lifetime and reliability. Using a magnet and a linear Hall-effect sensor instead to create a contactless linear position sensing implementation addresses these reliability issues.

To properly design a contactless Hall-based position sensing system, keep in mind the magnet-to-sensor orientation and device package type in order to build a contactless Hall-based linear movement sensing system.
