9.B1D30N Cembre EWO IP66 Black 1 hole 30 - 31mm cable clamp Grommet For Split Cable Entry Systems

Why Choose the Cembre EWO 9.B1D30N IP66 Black 1 Hole 30 - 31 mm Cable Clamp Grommet

The Cembre 9.B1D30N is a black single hole grommet for the EWO split cable entry system. It enables sealed routing of one 30 - 31 mm cable, delivering firm clamping and dependable strain relief while preserving the enclosure’s IP66 ingress protection in industrial panels, automation equipment, and OEM machinery.

Using the Type B medium module footprint, the 9.B1D30N clips into compatible EWO frames for a fast, tool free installation. It is interchangeable with Type B blanks and other drilled grommets, so layouts can be reconfigured later without reworking the panel cut out.
