What is the difference in waterproof performance between IP67 and IP68 ratings for J1939 cable connectors?

The IP67 and IP68 ratings of J1939 cable connectors have the following differences in waterproof performance:

Immersion depth

IP67： Can withstand immersion in water up to 1 meter deep.

IP68： It can be soaked in water deeper than 1 meter, with the specific depth specified by the manufacturer, generally up to 3 meters or deeper.

Soaking time

IP67： Usually 30 minutes.

IP68： The continuous soaking time can be longer, generally not less than 1 hour, and some can even meet the continuous soaking needs for several hours or even longer.

Waterproof ability

IP67： It can prevent water intrusion, but its protective ability is relatively limited in complex water environments such as high water pressure and water flow impact.

IP68： It can withstand higher water pressure and more complex water environments, such as water flow impact, water bubbles, etc., providing more reliable waterproof protection.

Application scenarios

IP67： Suitable for environments that may come into contact with water splashes or brief immersion, such as outdoor lighting fixtures, handheld devices that may occasionally fall into the water, etc.

IP68： Suitable for equipment that requires long-term immersion or high water pressure environment, such as underwater cameras, diving equipment, industrial equipment that works in humid or underwater environments for a long time, etc.
