  • LDC2112/LDC2114 Inductive Touch System Design Guide
    PDF, 3.0 Mb, Archivo publicado: feb 2, 2017
    The Inductive Touch System Design Guide presents an overview of the typical sensor mechanicalstructure and sensor electrical design for human machine interface (HMI) button applications. Themechanical design chapter discusses several factors that impact button sensitivity, including metalselection, sensor geometry, sensitivity dependence on target-to-coil distance, and mechanical isolation

  • Inductive Touch - Configuring LDC2114 Touch-Button Sensitivity
    PDF, 771 Kb, Archivo publicado: marzo 16, 2017
    Erroneous or unintended button presses can result in a frustrating user experience in a human machine interface (HMI). Capacitive touch buttons trigger anytime a grounded object is brought close to the button; this can often cause false or erroneous button presses. One advantage mechanical buttons have over capacitive touch buttons is that a certain amount of force must be applied on the buttons f
