Differences in dustproof levels
IP55 cabinet: Dustproof level is 5, which means metal wire protection (diameter greater than or equal to 1mm) and prevention of harmful dust accumulation, which means that dust cannot be completely prevented from entering, but the amount of dust entering will not affect the normal operation of the equipment.
IP65 cabinet: Dustproof level is 6, which means complete prevention of dust entry. When conducting IP6X testing, the sample needs to be vacuumed between the outer shell and the internal components to create a negative air pressure phenomenon, and then placed in a dustproof box for dustproof testing.
Waterproof level
IP55 and IP65 cabinets are both waterproof level 5, which can prevent water ejected from nozzles from all directions from entering the equipment and causing damage.
Differences in cabinet materials
IP55 cabinet: The outer shell is usually made of metal materials, such as steel or aluminum alloy, which can effectively isolate large particles of dust from entering the equipment, but cannot completely prevent liquid from penetrating. Its sealing elements use rubber sealing rings or coatings, which can prevent fine particles of dust and mist droplets from entering the equipment to a certain extent.
IP65 cabinet: The shell is made of engineering plastics, such as ABS or PC. This material has excellent protection performance and can completely prevent large particles of dust from entering the equipment, and can also effectively resist the intrusion of jet water. Its sealing elements usually use high-quality rubber sealing rings, which can effectively block the infiltration of tiny particles of dust and drizzle.
