Metal Capacitive Touch Panel with NFC for Elevator & HMI

概览

描述

As user experience (UX) improvements become increasingly important across various applications, elevators in office buildings and hotels are expected to deliver both high-end design and intuitive interfaces. By adopting capacitive metal touch buttons on the elevator control panel, this system achieves a sleek, fully flat metal overlay for a premium look while ensuring reliable operation—even with wet hands or gloves.

In safety-critical applications like elevators, communication between the control panel and the control module must be highly reliable. This system leverages CAN FD to provide robust communication and fast response times, minimizing the risk of accidents and enabling safe operation. Additionally, the system supports near-field communication (NFC) for card-based authentication, allowing secure and personalized access for elevator users.

System Benefits:​

  • Combines a premium control panel design with metal touch buttons that function even with
    wet hands or gloves​
  • Ensures high communication reliability and fast response through CAN FD​
  • Supports user authentication via NFC for enhanced security
