What do IP66 & IP67 mean?
Ingress Protection (IP) ratings define how effective a product is at preventing foreign objects from intruding during use. The first “6” in IP66 and IP67 refers to external protection from solid particles and signifies that a product is completely dust-tight. The second “6” in IP66 refers to protection from liquids from high-pressure spray downs for 3 minutes. The “7” in IP67 refers to protection from liquids in temporary submersion in water. Arrow Hart’s watertight plugs and connectors meet IP67 ratings when fully mated, and our receptacles meet IP66 ratings when the flip lid is completely closed and when a plug is fully mated. These combinations result in an excellent solution for heavy industrial applications and washdown environments making our Arrow Hart’s watertight devices perfect for food and beverage applications
