Resistive vs. PCAP Touchscreens in Industrial Automation: Liquid, Debris, and Glove Tolerance
Selecting the right touch interface architecture is one of the most critical decisions when deploying operator human-machine interfaces (HMIs) on the plant floor. Automation engineers frequently debate between two established sensing methodologies: 5-Wire Resistive and Projected Capacitive (PCAP). While consumer devices rely almost exclusively on capacitive glass, industrial operating conditions present environmental variables that challenge
