1. IP grade dust or object resistance rating (IPX*)
IPX0: no protection
IPX1: Prevent large solids from immersing
IPX2: Prevent medium-sized solids from invading
IPX3: Prevent small solids from immersing
IPX4: Prevent solids more significant than 1mm from entering
IPX5: Prevent harmful dust accumulation
IPX6: Completely prevent dust from entering
2. IP grade waterproof or moisture resistant grade (IP*Y)
IP0Y: no protection
IP1Y: Drops of water dripping into the casing have no effect
IP2Y: Water or raindrops from the 15-degree angle to the outer casing without affecting
IP3Y: Water or raindrops from the 60-degree angle to the outer casing without affecting
IP4Y: No impact on water at any angle
IP5Y: Low-pressure injection at any angle has no effect
IP6Y: High-pressure jet water has no effect
IP7Y: It can withstand water in a short time (15cm-1cm, within half an hour)
IP8Y: Soaking water for a long time under a certain pressure
The IP rating consists of two numbers, the first indicating dust protection and the second indicating water resistance. A more significant number indicates a better level of security.
