Cable Entry Systems for Control Cabinets and Machines
Murrplastik cable entry frames, plates and grommets route cables into control cabinets and terminal boxes, including cables with connectors already fitted. Strain relief plates and protection conduits complete the cable path. Our application engineers help you choose the right system for your cut-out and cable count.
Cable glands need one hole per cable and force you to cut off and re-terminate moulded connectors. The result is crowded panel walls, long assembly times, leaky entries and strain on the terminals when cables are pulled.
Types of cable entry systems
Split cable entry frames for pre-assembled cables
Splittable frames that let cables pass through with their connectors fitted, so no re-termination is needed. The KDL/C takes up to 48 pre-assembled cables; the KDL/H is a robust zinc die-cast or aluminium version.
Models: KDL/C · KDL/D · KDL/E · KDL/E+ · KDL/H
Cable entry grommets
Grommets fitted around the cable and then inserted into the frame, sealing the entry and providing strain relief. Double and multi-line grommets and AS-i bushings are available.
Models: KDT/X · KDT/ZE
Cable entry plates and membranes
Plates that fit standard connector cut-outs and take many cables through one opening, up to IP66/67 and IP69K on the KDP/Z (with matching cables and screwed). The KDM/F membranes fit metric cut-outs from M16 to M32.
Models: KDP/X · KDP/N · KDP/F · KDP/Z · KDM/F
Strain relief and cable fixing plates
Plates for holding cables and hoses with cable ties, on mounting plates, top-hat rails or C-rails, plus shield clamps for connecting cable shields to earth potential.
Models: Type ZL · ZL-AH · ZL-MH · ZL-AM · KAF · Type SK
Cable protection conduits
Flexible corrugated conduits for bundling and protecting cables on machines. The EWT versions are slit and can be opened and closed at any time, for pre-assembled cables and retrofits.
Models: EWX · EWL-PA · EWL-PAB · EWT-PA · EWT-PP
What to specify
| Parameter | What to check |
|---|---|
| Cables with or without connectors | For pre-assembled cables use a split frame (KDL series) with grommets. For cables without connectors, a cable entry plate or membrane is usually quicker. |
| Cut-out size | Most frames and plates fit standard 24-pin or 16-pin industrial connector cut-outs, so no special machining is needed. The KDM/F fits metric M16 to M32 holes. |
| Number and diameter of cables | Count the cables and list their diameters. Frames and plates pack many cables into one cut-out; grommets are chosen per cable diameter. |
| Protection class | Match the enclosure: IP54 on the KDL/C, IP65 on the KDP/X, KDP/N and KDP/F, up to IP69K on the KDP/Z for washdown areas. The rating depends on the right grommets and cables being fitted. |
| Strain relief | Decide whether strain relief is needed at the entry itself (integrated on the KDL/C, KDL/D and KDL/H) or inside the cabinet on a ZL or KAF plate. |
| Material and environment | Plastic frames for most panels; metal frames (KDL/H) for heavy machinery. Check temperature and UV exposure for outdoor installations. |

Common questions
Why use a split cable entry system instead of cable glands?
A split frame opens around the cable, so cables with moulded connectors can be fed into the cabinet without cutting them off and re-terminating. It also takes many cables through one standard cut-out, which saves space on the panel wall and assembly time.
How many cables fit in one cable entry frame?
It depends on the frame and the cable diameters. The KDL/C and KDL/H take up to 48 cables in one frame. Send us your cable list and we will work out the frame and grommets.
Do I need special cut-outs in the cabinet?
Usually not. Most Murrplastik frames and plates fit standard cut-outs for 24-pin and 16-pin industrial connectors, and the KDM/F membranes fit metric M16 to M32 holes.
Which cable entry is suitable for washdown areas?
The KDP/Z cable entry plate reaches IP66/67 and IP69K when fitted with matching cables and screwed in place, which suits washdown areas in food and pharma plants.
What is a strain relief plate used for?
It holds cables and hoses in place with cable ties, so pulling on a cable does not load the terminals or connectors. The ZL plates are screwed in place, the KAF snaps onto a 35 mm top-hat rail or C-rail.
