What does the IP number of the connector mean?

IP grade refers to the protection grade of the enclosure of electrical equipment against the intrusion of foreign matters, which is derived from the standard IEC of the International Electrotechnical Commission; the first mark number indicates the protection grade of contact protection and foreign matters; the second mark number indicates the protection grade of waterproof. In general, the degree of protection is the sealing protection of electrical equipment to prevent foreign objects (such as tools, dust, fingers) and humid gases from entering its enclosure. Many friends have asked me before, what does the number above the IP level mean. What is the meaning of the number above the IP level on the connector? When we choose a connector, how do we choose the connector that suits our IP level. After reading this article, I hope to help you. 1. Level of protection-the first number, the first number of the IP code indicates the degree of protection against human contact and moving parts and the prevention of solid foreign objects from entering the equipment enclosure 1-to prevent large parts of the body (such as hands) or to prevent solid objects with a diameter of more than 50 mm from entering 2-to prevent not more than 80 mm, Entry of objects with a diameter of 12mm 3-Prevention of entry of objects with a diameter or thickness of more than 2.5mm such as tools and wires 4-Prevention of entry of solid substances with a diameter or thickness of more than 1.0mm 5-Prevention of dust and scale affecting equipment operation 6-Complete dust-proof 2. Protection level-the second number. The first digit of the IP code indicates to avoid the entry of water in various forms (e. Immersion, etc.) The degree of protection of the equipment case 1-prevents water from dropping vertically 2-prevents water from dropping at an inclination of not more than 15 deg. 3-prevents water from being sprayed 4-prevents water from gradually entering 5-prevents water from being injected from the nozzle 6-prevents a large amount of sea water or water having a spray pressure from entering 7-prevents water from entering during a short immersion 8- Prevent water ingress during complete, continuous submergence (15 minutes submergence at a depth of at least 1 meter)
