Touch overlay is a transparent protective layer with touch-sensitive technology that enables user interaction with HMI screens in industrial environments.
A touch overlay is a specialized component installed over display screens in Human-Machine Interface (HMI) systems, incorporating capacitive, resistive, or surface acoustic wave technology to detect user touch inputs. It serves as both an interactive interface and protective barrier against environmental factors such as moisture, dust, chemicals, and mechanical impacts in industrial settings. The overlay typically consists of multiple laminated layers including a top hard coat for scratch resistance, conductive layers for touch detection, and adhesive layers for secure bonding to the display.

Capacitive overlays use conductive layers that detect touch through capacitance changes, offering multi-touch capability and better clarity. Resistive overlays use pressure-sensitive layers that make contact when pressed, providing higher durability and working with any stylus but with reduced optical clarity.
Use isopropyl alcohol (70% concentration) with a soft, lint-free cloth. Avoid abrasive cleaners, ammonia-based solutions, or excessive pressure that could damage the surface coating.
Yes, overlays can be customized with specific coatings (anti-glare, anti-fingerprint), shapes, connector types, and integration with protective bezels or mounting systems for particular industrial environments.
