Press: Cable entry made simple

Cable and connector entry in enclosures and housings is a small detail, but one that engineers often associate with a great deal of effort and annoyance. Now, Rittal has come to the rescue with its new plug inlet system. It allows cables of different diameters and pre-assembled plugs to be introduced without any tools, and fastened with much less effort. Unwanted cable movements caused by settling or twisting, as well as damage from edge pressure, which can lead to leaks and malfunctions, are now a thing of the past.

This new development is based on sealing frames, mounted on the enclosure and equipped with various sealing modules for cable and connector entry. This way, the sealing frames can be easily mounted on 24 or 16pole connector cut-outs. The sealing modules are fastened to the sealing frames with wire clamps so that they resist vibrations. To swap cables quickly, engineers need to only unlock just a few sealing modules. With larger connectors, several modules can be removed.

A further advantage: With installations that need to be disassembled for transport, the modules can remain attached to the cables. This way, the risk of parts getting mixed up or going missing can be avoided.

"Less is more!" - this motto applies here, too. Users require just two different modules for the clamping range that covers cable diameters from 4 to 9 mm. This not only minimises storage costs but also provides greater flexibility and planning predictability - especially if the exact cable diameter has not yet been decided upon.
The new cable entry system is of protection class IP 64 as per EN 60 529 and meets the requirements of NEMA 12. The sealing frames and modules are made of polyamide, the seal of LSE 2.
