What is an Industrial PC with Touchscreen?

An industrial PC with touchscreen is a specialized computing device designed to withstand harsh industrial environments while providing intuitive, touch-based user interaction. Unlike standard office computers, Panel-PCs used in industry are robust, reliable, and can endure extreme temperatures, dust, moisture, and high mechanical stress. They are often implemented as HMI (Human Machine Interface) systems, making them central to modern automation and IoT setups in factories, logistics, medical, and food processing environments.

These systems integrate a display (7–55 inches), processing unit (e.g., Intel Core, Celeron, or Pentium), and are engineered for long-term, fanless operation. Typical variants include the IP65 Panel-PC for general industrial use, as well as models offering higher protection such as IP69K for demanding sectors. The flexibility of these computers, enhanced by multi-touch capabilities and compatibility with various operating systems like Windows and Linux, make them ideal for both standard and custom industrial applications.

Touch Technologies Compared: Capacitive vs. Resistive

The heart of a Touch Panel PC is its touchscreen. Two primary technologies dominate in industrial usage: capacitive and resistive touchscreens. Each has unique strengths and is suited to different application scenarios.

Capacitive Touchscreen

• Delivers a modern, glass-like surface with robust multi-touch capability (gestures like zoom and swipe).
• Enables intuitive operation, similar to smartphones and tablets.
• Excellent light transmission and color clarity.
• Typically supports gloved fingertips (depending on model) — ideal for operators working with protective equipment.
• Best suited for clean, dry, or moderately humid environments.

For industrial environments demanding ultra-hygienic, easily cleanable HMIs, capacitive touch is often paired with stainless steel housings and high protection classes (IP65, IP69K).

Resistive Touchscreen

• Based on pressure sensitivity, allowing operation with any pointed object — gloves, styluses, or bare hands.
• Can be reliably used even in wet or dirty conditions, making them ideal for food processing or heavy industry.
• Slightly less light transmission compared to capacitive screens, but highly durable and forgiving of contaminants.
• Limited to single-touch operation (no multi-touch gestures).

Many projects combine both technologies in their industrial PC configuration, selecting based on the specific operational context.

Technical Features and Protection Classes

Industrial PCs stand out due to their rich set of technical features and compliance with strict industrial standards. Key technical characteristics include:

• Display Size: Available in a wide spectrum from compact 7″ up to 55” displays to fit various control panels and monitoring stations.
• Protection Class: Encased for dust-/water-resistance with ratings up to IP69K for washdown and sterile zones; IP65 Panel-PCs are standard in most industrial settings.
• Temperature Range: Designed to operate from -20°C up to +60°C and beyond, ensuring reliability even in freezing or high-temperature environments.
• Enclosure: Rugged stainless steel or aluminum housings guarantee long-term corrosion resistance and chemical stability.
• Fanless Design: Passive cooling reduces dust ingress and noise, prolonging component life.
• Processors: Latest Intel Core, Celeron, or Pentium CPUs tailored to the application’s performance needs.
• Hygienic Design: Sealed enclosures, flush surfaces and rounded edges to meet stringent requirements in food and pharma industries. For more details on compliance and validation, see EMC certified hardware requirements.
