Understanding IP66

What Is an IP66 Enclosure?

IP66 stands for Ingress Protection 66, an international standard (IEC 60529) that tells you exactly how well a product is protected from the outside world.

IP Code DigitWhat It Protects AgainstIP66 Rating Means
First "6"Solid particles (dust, dirt, debris)Completely dust-tight
Second "6"Liquids (water, moisture)Protected against powerful water jets from any direction
An IP66-rated enclosure won't let in a single speck of dust, and it can handle a high-pressure hose blasting water at it from any angle. That's the level of protection your critical electrical gear deserves when it's sitting outside on a factory floor, offshore rig, or telecom tower.

About the HA Series

They're protection systems for the equipment that keeps your operations running — including industrial network switches, media converters, PLC modules, terminal blocks, and communication gear.
