Requirements for the protection grade of vacuum pressure switches

The protection level requirements for vacuum pressure switches need to be determined in combination with the usage scenarios. The following is a specific analysis:

The Protection grade is a standard used to indicate the dust-proof and water-proof capabilities of the casing of electrical equipment, represented by IPXX. Here, IP stands for Ingress Protection, and the following two digits represent the dust-proof grade and water-proof grade respectively. The dust-proof level ranges from 0 to 6. The larger the number, the better the dust-proof ability. 6 indicates complete prevention of dust from entering. The water resistance rating ranges from 0 to 8. The higher the number, the stronger the water resistance. An 8 indicates that it can be immersed in water for a long time under certain pressure.

When choosing a vacuum pressure switch, if the equipment needs to operate in an environment with abundant rainfall or high humidity, it is recommended to select a product with an IP65 rating or above. For instance, the HYP series vacuum pressure switches produced by Yichang Huicheng Automation Equipment Co., Ltd. feature a cast aluminum housing with a protection level of IP65. They are waterproof and dustproof, have good strength and anti-interference performance, and can be used in harsh environments, making them suitable for professional industrial control sites. For instance, the vacuum pressure switch of SSI in Canada also has a protection grade of IP65. In addition, the protection level of the Italian CELLA vacuum pressure switch PCS2VC is as high as IP66, meeting the NEMA4X standard.
