The IP rating can be seen on many sensors’ product logos and manuals, and even Apple’s cell phone has proposed an IP67 protection rating. So what is the IP rating, IP67 represents and what is the meaning of it? Sensor in the IP protection rating system is the electrical appliances according to its dust and moisture characteristics to be graded and composed of two numbers. The first digit indicates the level of protection of the appliance against dust and intrusion of foreign objects, and the highest level is 6. Numbers Protection range Description 0 No protection No special protection against external persons or objects. 1 Protected against solid foreign objects larger than 50mm in diameter. Prevents accidental contact of the human body (e.g. the palm of the hand) with internal parts of the appliance, and prevents intrusion of large-sized foreign objects (diameter greater than 50 mm). 2) Preventing the intrusion of large-sized objects (diameter greater than 50mm) Prevents the intrusion of solid objects larger than 12.5mm in diameter. Prevents human fingers from coming into contact with parts inside the appliance, and prevents the intrusion of medium-sized (diameter greater than 12.5mm) foreign objects. 3 Prevents intrusion of solid foreign objects larger than 2.5mm in diameter. Prevents tools, wires, and similar small objects with a diameter or thickness greater than 2.5mm from coming into contact with the internal parts of the appliance. 4 Prevents intrusion of solid foreign objects with a diameter greater than 1.0mm. Prevents tools, wires and similar small foreign objects with a diameter or thickness greater than 1.0mm from coming into contact with the internal parts of the appliance. 5 Protection against foreign matter and dust It prevents the intrusion of foreign objects completely, and although it does not prevent the intrusion of dust completely, the amount of dust intrusion does not affect the normal operation of the appliance. 6 Protection against foreign objects and dust Completely protected against foreign objects and dust. The second digit indicates the degree of airtightness of the appliance against moisture and water ingress, and the higher the number, the higher the level of protection. The highest level is 8. Numbers Protection range Description 0 No protection No special protection against water or moisture 1 Protection against water droplets Vertically falling water droplets (e.g. condensation) do not cause damage to the appliance 2 Protected against water drops when tilted at 15 degrees When the appliance is tilted from vertical to 15 degrees, dripping water will not damage the appliance. 3 Protected against immersion of sprayed water Prevents rain or water sprayed in a direction less than 60 degrees from the vertical from penetrating into the appliance and causing damage. 4 Protection from splashing water Protect the appliance from damage caused by splashing water from all directions. 5 Protect against splashing water Protected against low-pressure water jets lasting at least 3 minutes. 6 Protected against large waves Protected against large jets of water lasting at least 3 minutes 7 Protected against water ingress during immersion Protection against the effects of immersion in water up to 1 meter deep for 30 minutes 8 Protection against immersion of water during submersion Protection against the effects of continuous immersion in water more than 1 meter deep. The exact conditions are specified by the manufacturer for each device. Each model of Star Instruments’ pressure sensors, level sensors, differential pressure sensors, temperature sensors, temperature and humidity sensors, and soil moisture sensors is labeled with a specific level of protection. To provide customers with specific selection programs for different applications. Star Instruments sensors have also obtained the relevant industry testing and inspection reports. To provide customers with peace of mind, high quality sensors. All we will not be difficult to understand. IP67 means: completely prevent the intrusion of foreign objects and dust, and in the depth of 1 meter of water to prevent the impact of 30 minutes of immersion. Star Instruments Sensor Technology Co., Ltd. is a collection of research and development, production, sales as one of the high-tech enterprises.
