Understanding the IP67 protection rating for HMIs
Date: 14/02/2025
WHAT DOES IP67 MEAN?
Definition of the IP67 rating
The IP67 rating comes from the IEC 60529 standard. It demonstrates how well a device protects against solid objects and liquids.
First digit (6): Full protection against dust and solid particles, ensuring no internal contamination.
Second digit (7): Resistance to temporary immersion in water, withstanding depths of up to 1 meter for 30 minutes.
These features make IP67-rated devices dependable in environments with exposure to dust, moisture, or temporary submersion.
How to read an IP rating? (IP6X and IPX7)
An IP (Ingress Protection) rating has two digits, each signifying protection levels.
The first digit, such as the “6” in IP67, means the device is fully dust-tight.
The second digit, “7,” highlights water resistance, allowing the device to handle brief water exposure without damage.
Combined, these digits demonstrate robust performance across industries requiring reliable protection.
DIFFERENCES BETWEEN IP67 AND OTHER RATINGS (IP65, IP66, IP68…)
IP65 vs. IP67: dust and liquid protection
IP65 offers protection against low-pressure water jets and dust ingress, but it is not dust-tight. IP67 offers complete dust protection and can handle water immersion. This makes it better for places with a lot of dust and some water exposure.
Comparison with IP66: differences in water resistance
While both IP66 and IP67 offer full dust protection, their water resistance varies. IP66-rated devices can resist powerful water jets, but they do not receive a rating for immersion. IP67 adds the capability to withstand submersion in water, expanding its use cases.
IP67 vs. IP68: applications for prolonged immersion
The main difference between IP67 and IP68 lies in the water resistance duration and depth. IP68 allows for prolonged immersion at greater depths, often specified by the manufacturer. This makes IP68 suitable for underwater applications, whereas IP67 is designed for temporary immersion.
APPLICATIONS OF THE IP67 RATING IN HUMAN-MACHINE INTERFACES
Reliable performance in harsh environments
IP67-rated HMIs are designed to operate in dusty, wet, and outdoor conditions, making them ideal for:
Construction machinery: Excavators, loaders, and cranes exposed to dust and rain.
Agricultural equipment: Tractors, irrigation systems, and sprayers operating in muddy conditions.
Special vehicles: Fire trucks,military transport, and utility vehicles needing waterproof IP-rated controls.
Public infrastructure: Roadside equipment, electric vehicle charging stations, and traffic management systems.
