Projective capacitive (PCAP) touchscreens are perfect for industrial applications because the touch performance is unaffected by dust, dirt and scratches on the screen. It can be fully sealed for high ingress protection and has a high resistance to scratches, chemicals, liquids and other surface contaminants, such as dust, moisture, grease and oil. The PCAP screen consists of a sheet of glass with a thin film and an integrated sensor to recognize changes in its electromagnetic field which detects your finger position. PCAP touchscreens also have multi-touch technology, which is the simultaneous input from two or more fingers. This enables pinch to zoom and rotate capabilities.
