Phoenix Contact offers a plethora of industrial connectivity products and accessories, including DIN rail such as 0801733. We’ve had a number of questions on this product concerning color variations in its finish, and whether these variations indicate manufacturer defects. Is this true?
Fortunately, no. The manufacturing and passivation process that Phoenix uses for these products naturally results in varied hues; these are considered purely aesthetic and do not impact functionality or specifications at all. You’re clear to use “off-color” rails freely.
