| IP67 | Dust-tight, protected against immersion in water | Harsh environments, outdoor kiosks | Submersion protection |
| IP68 | Dust-tight, protected against continuous immersion | Underwater use, extreme conditions | Long-term immersion capabilities |
| IP69K | Dust-tight, protected against high-pressure steam cleaning | Food processing, sanitation environments | High-pressure and high-temperature resistance |
Understanding Ingress Protection Ratings
What is Ingress Protection (IP) Rating?
The Ingress Protection (IP) rating system is an internationally recognized method to classify the degrees of protection provided by electrical enclosures against foreign objects and moisture. The rating is usually represented by the letters “IP” followed by two digits, where the first digit indicates protection against solid objects, and the second digit denotes protection against liquids.
Common IP Ratings Explained
- IP65: This rating indicates that the device is dust-tight and can withstand water jets from any direction. Perfect for environments with light exposure to water.
- IP66: Provides similar dust protection but can also withstand powerful water jets, making it ideal for marine applications.
- IP67: Offers protection against submersion in water up to 1 meter for a limited time, suitable for harsher environments.
- IP68: This rating allows for continuous immersion in water, which is essential for underwater applications.
- IP69K: The highest standard, protecting against high-pressure and high-temperature water, making it suitable for industrial cleaning processes.
Types of Waterproof Touchscreens and Their Features
Capacitive Touchscreens
Capacitive touchscreens utilize the electrical properties of the human body to detect touch. They are highly responsive and can work even with protective glass over the screen, making them suitable for outdoor applications. The 892GFC from Xenarc Technologies is an excellent example, featuring a 1000 NIT brightness for visibility in direct sunlight.
Resistive Touchscreens
Resistive touchscreens work by measuring pressure on the screen. They are less responsive than capacitive screens but are known for their durability and ability to work with gloves or styluses. These displays are often used in industrial settings where gloves are standard.
Projected Capacitive Touchscreens
These screens combine the best of both worlds, offering the sensitivity of capacitive screens while allowing for multi-touch capabilities. They are particularly effective in environments that demand high responsiveness, such as kiosks and control panels.
Applications of Waterproof Touchscreens
Marine Environments
Waterproof touchscreens are essential in marine applications, where exposure to water and salt can damage standard screens. Devices like those from Xenarc are designed to withstand harsh marine conditions, providing reliable performance on yachts and fishing boats.
Industrial Settings
In factories and manufacturing plants, equipment is often exposed to liquids and dust. Waterproof monitors from companies like Beetronics offer robust solutions that can handle the rigors of these environments.
Outdoor Displays
Outdoor kiosks and displays require screens that can endure various weather conditions. The high brightness ratings and protective features of waterproof touchscreens make them ideal for outdoor advertising and information panels.
Food Processing
The food industry demands stringent hygiene standards, which makes IP69K-rated touchscreens vital for sanitation. These monitors can withstand high-pressure cleaning, ensuring they remain clean and functional.
