Key Points for Selecting Waterproof and Dustproof Ratings of Industrial Connectors

Key Points for Selecting Waterproof and Dustproof Ratings of Industrial Connectors

1. Core Understanding of IP Rating Coding

1. Coding Rule: The two digits after "IP" represent the dustproof rating (first digit) and waterproof rating (second digit) respectively. A higher digit indicates stronger protection performance.

2. Dustproof Rating (Level 0-6): The highest level is Level 6, which can completely prevent dust intrusion.

3. Waterproof Rating (Level 0-9K): Among common levels, Level 6 resists powerful water jets, Level 7 withstands short-term immersion (1m depth/30 minutes), Level 8 endures continuous immersion under specified pressure, and Level 9K resists high-temperature and high-pressure water flushing.

2. Selection Guide for Different Scenarios

1. Dry and Low-Dust Environments (e.g., general workshops, inside control cabinets): Choose IP54, which can resist most dust and splashing water.

2. Outdoor Rain-Exposed Environments (e.g., outdoor lighting, open-air sensors): Choose IP67, suitable for short-term rain exposure or shallow water immersion scenarios.

3. Humid, Dust-Rich/Fluid-Flushing Environments (e.g., chemical workshops, sewage treatment plants): Take IP68 as the minimum standard; for scenarios requiring high-temperature and high-pressure flushing such as food processing and car washing, choose IP69K.

3. Easily Overlooked Key Notes

1. Pay attention to "additional conditions": The protection effect of IP68 is related to the specific immersion depth and duration. Confirm whether the parameters match your needs when purchasing.

2. Attach importance to "dynamic protection": For connectors that are frequently plugged and unplugged, check if the seals age after long-term use to ensure the protection rating remains effective.
