The IP Protection Rating (Ingress Protection Rating) is an international standard by the IEC measuring a robot or device’s ability to resist dust and liquids. Ratings consist of “IP” followed by two digits, e.g., IP67.
First Digit: Dust Protection Level
| Rating | Protection Level | Example | Typical Robot/Equipment |
| IP0X | No dust protection | Dust freely enters | Indoor outlet |
| IP1X | Objects ≥50mm | Finger contact protection | Old table lamp switch |
| IP2X | Objects ≥12.5mm | Prevents finger insertion | Indoor AC unit |
| IP3X | Objects ≥2.5mm | Blocks tools/wires | Outdoor streetlight |
| IP4X | Objects ≥1mm | Blocks insects/small debris | Industrial control box |
| IP5X | Dust-proof, minor ingress | Dust coating design | Indoor/outdoor surveillance robot |
| IP6X | Complete dust protection | Desert/construction sites | Smartphones, rugged robots |
Second Digit: Water Resistance Level
| Rating | Protection Capability | Example | Typical Robot/Equipment |
| IPX0 | No protection | Can be damaged | Office PC |
| IPX1 | Vertically dripping water | Condensation | Toys |
| IPX2 | Drips ≤15° angle | Light rain | Basic watches |
| IPX3 | Rain ≤60° | Balcony/outdoor speaker | Outdoor inspection robots |
| IPX4 | Splash from any direction | Kitchen/wash area | Роботы-уборщики |
| IPX5 | Water jets | Short-term rinsing | Industrial fan robots |
| IPX6 | Powerful water jets | Waves, outdoor exposure | Surfing/action robots |
| IPX7 | Short-term immersion | ~30 min/1 m depth | Smartphones, delivery robots |
| IPX8 | Continuous immersion | Depth/duration specified | Diving robots |
| IPX9K | High-temp, high-pressure jets | Steam cleaning | Food processing robots |
Example Analysis
| IP Rating | Analysis | Заявка | Features |
| IP65 | Dust-tight + water jets | Outdoor power enclosure | Fully dustproof & water-resistant |
| IP67 | Dust-tight and short immersion | Bluetooth headphones | Fully dustproof, short-term immersion |
Tips for Choosing the Right IP -Rated Robot
| Окружающая среда | Recommended IP Rating | Причина | Example Robot |
| Indoor dry warehouse/office | IP4X–IP5X | Low dust & minimal water | Indoor delivery robots |
| Indoor wet areas (kitchen/lab) | IP5X–IPX5 | Protects against splashes | Food processing robots |
| Outdoor light rain/dust | IP65 | Dustproof & water jet resistant | Delivery/inspection robots |
| Outdoor heavy rain/construction | IP66–IP67 | Short-term immersion protection | Agricultural robots |
| Water/pond/irrigation areas | IPX7–IPX8 | Short-term or continuous immersion | Irrigation monitoring robots |
| High-pressure water/sterilization | IPX9K | Industrial cleaning safe | Industrial cleaning robots |
Selection Tips:
- Match the IP rating to the actual operating environment.
- Consider robot function and electronics sensitivity.
- Avoid over-specifying to reduce costs.
Maintenance Tips for IP -Rated Robots
- Inspect Seals & Gaskets: Replace cracked or worn seals immediately.
- Dust & Debris Cleaning: Use soft brushes or a vacuum for sensitive areas.
- Check for Water Ingress: Inspect after exposure to rain or water.
- Test Moving Parts: Lubricate joints, wheels, and actuators.
- Electrical & Sensor Checks: Ensure connectors, LiDAR, and cameras remain sealed and clean.
- Software & Monitoring: Use diagnostic systems for exposure tracking.
- Storage Practices: Keep robots in dry, clean locations away from sunlight or water.
- Optional Immersion Testing: Test IPX7–IPX9K robots occasionally for critical applications.
Часто задаваемые вопросы
What does IP67 mean for a mobile robot?
IP67 means the robot is fully dustproof (6) and can survive short-term immersion in water up to 1 meter for 30 minutes (7).
Can an IP65 robot operate in heavy rain?
IP65 can resist water jets, but prolonged submersion may damage electronics. IP66–IP67 is better for heavy rain.
How often should I inspect seals and gaskets?
Every 3–6 months for regular use; more often in dusty or wet environments.
Does a higher IP rating guarantee no maintenance?
No. All IP-rated robots require regular cleaning, inspection, and sensor maintenance.
Can I upgrade a robot’s IP rating?
Only partially; physical enclosures and seals define the rating, so retrofitting has limits.
Are IP ratings the same for all components?
Not always. Sensors, connectors, or batteries may have different IP levels; always check the weakest component.
Is IPX9K necessary for outdoor robots?
Only if the robot faces high-pressure cleaning or industrial sterilization. For most outdoor robots, IP65–IP67 is sufficient.
How does IP rating affect robot cost?
Higher IP ratings increase enclosure complexity and costs but improve durability and reduce downtime in harsh environments.
