Will using a cable gland through a knockout affect the enclosure's IP rating?

Short answer

Using a cable gland through a knockout does not affect an enclosure's IP rating, provided the gland's own rating matches or exceeds it. Spelsberg's cable gland range is rated IP68, and gland/enclosure spec sheets are available to confirm compatibility for a specific installation.

The IP rating of an enclosure will not be effected as long high IP rated cable glands are used. All of Spelsberg cable glands are rated IP68. Please see the link below for Spec sheet and drawing.
