How can we help you today?

What is the IP rating of the Harmony XB4 & XB5 ranges?

The XB4 and XB5 products are IP66, IP67, IP69 and IP69K.

They are listed as such because the tests for IP*6, IP*7, IP*9 & IP*9K have different requirements, and having all of the ratings listed indicates that the products have passed each individual test. Please see the table below for the definitions of each IP rating.

You may notice that IP69 and IP69K are listed separately, but only 1 test for these exists. This is because IP69 is tested from an IEC standard and is for electrical equipment, while IP69K is testing from an ISO standard and is for electrical equipment mounted on road vehicles. One such application for IP69K regarding Harmony XB4 & XB5 products is on refuse collection vehicles.
