With the development of society and the advancement of science and technology, people’s requirements for high-quality life are getting higher and higher. From intelligent kitchen and bathroom, shared equipment, new energy vehicles and other industries, all industries are following the requirements of society, from product design to product design. From the stage to the end customer use, the after-sales service in the later stage is improving. For the stability and reliability of the product, the requirements for the control #switch-micro switch in the equipment are getting higher and higher, from ordinary #microswitches to dust-proof micro switches. Motion switches, up to the current waterproof #microswitches, require at least IP67 and IP68 grades. zjshuyi will take you today to learn the difference between dustproof and waterproof grades. Protection grades are mostly expressed by IP followed by two numbers. to define the level of protection.
IP (English name Ingress Protection) protection level standard was drafted by IEC, the purpose is to classify electrical appliances and other equipment according to their dustproof and waterproof characteristics. The IP protection level is composed of two numbers. The first marked number represents the level of the electrical appliance against dust and foreign objects intrusion. The second marked number represents the degree of airtightness of the electrical appliance against moisture and water intrusion. The larger the number, the higher the protection. The higher the level. (The foreign objects referred to here include tools, human fingers, etc., and should not touch the live parts of the electrical appliance to avoid electric shock)
Environmental requirements have a great influence on the selection of #microswitches, especially in applications requiring high reliability and criticality such as industrial control and medical equipment. Understand the environmental conditions of the application, including contaminants in the air that may enter the switch, the liquid in which the switch is located, and operating temperature requirements.
For applications in harsh environmental conditions, you need to choose a sealed switch with a wide operating temperature range. Highly reliable #microswitches can operate in the temperature range of -65°F (-54°C) to 350°F (177°C), making it easy to handle a variety of applications. At the same time, it should also be noted that the protection level of the switch should be at least IP67 to prevent liquid intrusion. This eliminates the need to spend a lot of time designing an enclosure that achieves the same degree of protection.
