Azoteq Waterproof Inductive Slider Interface

https://www.futureelectronics.com/m/azoteq. Azoteq uses inductive technology to design a completely waterproof slider interface. Inductive coils on the PCB detect the absolute position of a metal object. All electronics can be sealed away from water and dust while the coils detect the movement of the metal object outside the housing. https://youtu.be/MnxUmLFllhU
