IP67 protection is a standardized rating that defines how well an industrial device is sealed against dust and water. In Panel PCs, this rating is achieved through a combination of mechanical design, material selection, and sealing technologies that ensure the internal electronics remain fully protected even in harsh environments.
The “IP” stands for Ingress Protection, a global standard used to classify the level of protection provided by electrical enclosures. The two digits after “IP” represent different protection levels:
6 (first digit): Completely dust-tight. No dust can enter the enclosure, even in high-dust industrial environments.
7 (second digit): Protected against temporary immersion in water up to 1 meter for 30 minutes under controlled conditions.
For Panel PCs, this means the system can operate reliably in environments with heavy dust exposure and occasional water immersion or strong washdowns.
To reach IP67 certification, manufacturers use multiple engineering techniques that work together to block any possible entry points for dust or water.
A fully sealed enclosure is the foundation. The housing is typically made from aluminum alloy or stainless steel, designed as a closed structure without unnecessary openings.
All joints and seams are protected with industrial-grade gaskets, often made from silicone or rubber materials. These gaskets compress tightly when the device is assembled, preventing liquid or particle penetration.
Touchscreen integration is another critical area. IP67 Panel PCs use edge-bonded displays where the glass panel is permanently sealed to the front housing. This eliminates gaps where moisture could enter.
External connections are one of the most vulnerable points in any electronic device. In IP67 Panel PCs, traditional ports like USB or Ethernet are replaced or covered with waterproof connectors.
Common solutions include:
M12 industrial connectors
Waterproof aviation plugs
Sealed cable glands with rubber protection
In some designs, I/O ports are relocated to the rear and covered with sealed caps to maintain full protection during operation.
IP67 Panel PCs are almost always fanless. Traditional cooling fans introduce air circulation, which can bring dust and moisture inside the system. Instead, passive cooling is used.
Heat is dissipated through the metal housing using heat pipes or internal thermal conduction systems. This ensures stable temperature control without compromising sealing integrity.
Inside the unit, components are often coated with protective layers to resist humidity and corrosion, further enhancing long-term reliability.
To qualify as IP67 rated, Panel PCs must pass standardized laboratory tests.
For dust protection, devices are placed in sealed chambers with fine dust particles for extended periods. After testing, inspectors verify that no dust has entered the enclosure.
For water resistance, the device is submerged in water under controlled depth and time conditions. After removal, it must continue to function normally without any internal damage.
Only devices that pass both tests are officially certified as IP67 compliant.
In real-world industrial environments, equipment is often exposed to extreme conditions such as high-pressure cleaning, airborne particles, humidity, and temperature fluctuations.
Without IP67 protection, Panel PCs are at risk of short circuits, corrosion, or performance degradation. With proper sealing, they can operate continuously in environments like food processing plants, outdoor kiosks, marine systems, and heavy manufacturing lines.
IP67 protection in Panel PCs is not a single feature but a complete system-level engineering approach. It combines sealed housing, waterproof interfaces, fanless architecture, and rigorous testing to ensure reliable operation in dust- and water-heavy environments.
This makes IP67 Panel PCs a critical choice for industries where downtime, contamination, or equipment failure is not acceptable.
