IP67 standard


IP67 refers to the level of protection security. IP is an abbreviation for Ingress Protection Rating (or International Protection code), which defines an interface's ability to protect against liquid and solid particles. IP followed by 2 digits, the first is the solid state protection level, the range is 0-6, respectively, indicating protection against large particles of foreign matter to dust; the second is liquid protection level, the range is 0-8, respectively Protection against vertical water droplets to underwater pressure. A larger number indicates a stronger ability. The IP67 is explained by the protection of dust inhalation (to prevent contact overall, to protect against dust penetration); to protect against brief immersion (anti-immersion). Currently the highest implementation in the cabling industry is the IP68 level. In addition, industrial connectors have temperature, seismic and other considerations for other harsh environments.

First characteristic
Protection level (first number in the code)
6 Dust imprisonment: dust can not enter the entire diameter of the object can not exceed the gap of the outer casing
Second characteristic
Protection level (the second number in the code)
7 Anti-short immersion: Under normal temperature and pressure, when the outer casing is temporarily immersed in 1M deep water, it will not cause harmful effects.
