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.
