Inductive Touch Stainless Steel Keypad Reference Design for Waterproof/Noise Immune HMI Applications

Description

This 16-button stainless steel keypad: which utilizes TI's inductive touch technology: demonstrates highly sensitive buttons on a single piece of 0.6mm thick stainless steel metal.  The design utilizes a MUXed approach to implement many buttons with a single LDC1614. The design is applicable to any metal or non-metal surface completely enclosing the system: enabling a sleek waterproof (IP67) design.

Features
  • Completely enclosed design with 0.6mm thick stainless steel panel as the button interfaceHigh sensitivity to measure metal movement in the sub-micrometer resolutionMeasures force applied to implement multiple functions on a single buttonRobust contactless design immune to water: dirt: dust: and other environmental contaminantsLow-cost design using PCB coils as the sensor
