Ordinary touchscreens are vulnerable in harsh environments such as factory floors with heavy forklift operations, nighttime streets where automatic ticket machines are subject to intentional vandalism, and during high-speed chases in police patrol cars, where vibrations are intense. This vulnerability can lead to significant downtime costs and potential safety hazards. While you may be familiar with the IP (Ingress Protection) rating, which assesses the protection of electrical equipment against dust and moisture, you might be wondering what the IK rating represents. Today, we will explore this topic together.
The IK rating is a standardized measure of an equipment enclosure’s (such as a touchscreen) resistance to mechanical impact, particularly for devices potentially exposed to harsh environments. Among the various IK ratings, IK10 represents the highest level of protection. Touchscreens rated IK10 are therefore the proven choice for applications demanding extreme durability. Whether in public settings or industrial environments, these screens deliver superior reliability.
IK10 touchscreens are specifically designed to withstand significant mechanical impact. According to the international standard IEC 62262, an IK10 rating requires the equipment to endure an impact energy of 20 joules. To visualize this, imagine a 5kg object dropped directly onto the screen from a height of 40 centimeters, with the screen sustaining no damage that compromises its operation or safety.
This exceptional impact resistance makes IK10 touchscreens ideally suited for high-risk environments. Whether facing accidental collisions or deliberate vandalism, these screens maintain both functionality and safety after impact, ensuring continuous operation in critical situations.
| IK code | IK01 | IK02 | IK03 | IK04 | IK05 | IK06 | IK07 | IK08 | IK09 | IK10 |
| Impact energy (Joule) | 0.14 | 0.20 | 0.35 | 0.50 | 0.70 | 1.00 | 2.00 | 5.00 | 10.00 | 20.00 |
Speaking about the history of IK Level or Rating, IK ratings are related to the European standard EN 62262 for touchscreens, which is the same as the international standard IEC 62262 (2002). This is a global numeric rating for the levels of defense offered by electrical equipment enclosures against outside mechanical impacts. It offers a way to describe how well an enclosure can shield its contents from outside influences. The European Standard BS EN 50102 first defined the capacitive touch panel IK Code (1995, amended 1998). The European standard was given the new number EN 62262 after becoming an international standard in 2002.
A piece of electrical equipment must meet the requirements of Standard EN 62262 for its impact strength or resistance to external mechanical stress when subjected to certain shocks. The EN 62262 standard simply specifies the impact amount of energy; the EN 60068-2-75 specification contains details on the test circumstances and process.
The Foundation: Toughened Glass Impact Resistance
The core defense against high-intensity impacts lies in advanced glass technology. Toughened glass (chemically or thermally strengthened) undergoes transformative processing: Rapid heating to 700°C followed by instantaneous cooling creates compressive surface stress, boosting impact resistance to 5x that of standard glass.
When struck, this prestressed structure absorbs and disperses energy, dramatically reducing breakage likelihood. Even upon catastrophic failure, it fragments into granular chunks rather than sharp shards, ensuring inherent safety. With surface hardness exceeding 7H on the Mohs scale, its scratch resistance preserves optical clarity and extends functional lifespan.
The Enabler: Optical Bonding Structural Enhancement
Optical bonding unlocks the next tier of impact performance. This process laminates the cover glass to the display panel using optically clear adhesive (OCA) or liquid optically clear adhesive (LOCA), eliminating failure-prone air gaps. By removing these voids, impact forces distribute uniformly across the composite structure instead of concentrating at weak points.
When designing or selecting a custom IK10 vandal-proof touchscreen, material performance must be prioritized. The core protective layer requires 6mm-thick chemically toughened glass – the fundamental safeguard for withstanding 20 joules of impact energy.
Correspondence between IK level and thickness:
For outdoor or high-illumination environments, anti-glare (AG) etching is mandatory. This surface treatment uses micron-scale texturing to scatter light, reducing reflectivity to <5% while minimizing visual fatigue, ensuring sustained visibility under 10,000lux lighting.
Touch response speed must match protection performance, and it is recommended to choose advanced copper metal mesh capacitive touch technology. It enables the touch screen to provide high precision and high responsiveness, while also supporting multi-touch and wet hand operation. This is essential to maintain smooth and accurate user interaction, even through a thick and durable glass layer.
IP (Ingress Protection) ratings are different from IK ratings in that IP ratings focus on moisture and dust protection, while IK ratings focus on mechanical shock resistance. The two are often used in conjunction to ensure that a device is fully protected from a variety of harsh conditions.
– Enhanced Durability: Properly matched IK levels ensure that touch screens can withstand impacts without compromising functionality.
– Extended Lifespan: Thicker touch screens with higher IK ratings often last longer, reducing replacement and maintenance costs over time.
– Improved User Safety: In public or industrial settings, where accidental impacts are common, properly protected touch screens enhance user safety by minimizing the risk of damage or injury.
Industrial settings, such as manufacturing plants, warehouses, and construction sites, expose equipment to harsh conditions, including vibrations from heavy machinery, accidental tool drops, and environmental wear. IK10 industrial touch displays are engineered to thrive in these scenarios due to the following advantages:
IK10 touchscreens are built to endure high-impact forces, making them resilient against accidental collisions or deliberate damage. The use of 6mm or 8mm toughened glass, often fully laminated, enhances their ability to resist scratches, cracks, and abrasions.
Industrial touchscreens must operate reliably under extreme conditions, such as high humidity, dust, or temperature fluctuations. IK10 screens, often paired with high IP ratings (e.g., IP65), provide comprehensive protection against both mechanical and environmental stressors. This durability minimizes downtime and maintenance costs, which are critical concerns in industrial operations.
IK10 touchscreens are available in various configurations, including:
Open-frame displays: Ideal for integration into custom enclosures, such as vending machines or kiosks.
Panel-mount displays: Designed for flush installation in control panels, common in factory automation.
Chassis-mount displays: Encased for added protection, suitable for rugged outdoor or industrial use.
