chainfix strain relief: clamps

Strain relief for cables in energy chains with clamps and stacker elements

The principle of clamps as strain relief has proven very successful for cables in energy chains. Clamps are a suitable means of strain relief for all energy chains with a KMA mounting bracket and C-rail option.

Product range and materials

Steel clamp: clamp and screw black painted steel
Stainless steel clamp: clamp and screw: blank (material 1.4301)
Stacker elements: bottom saddle and stacker saddle (igumid G material)
C-profiles: steel (material galvanised steel) or stainless steel (material 1.4301) available

Tech up

3.5 times higher force absorption than standard clamps
Painted steel or stainless steel
For two different C rail sizes
CFX standard clamps with normal base and CFXL clamps with wide base for increased holding force available

Cost down

Cost-effective standard component
Easy to retrofit
Cost-effective strain relief for large hose and cable diameters
Space and time-saving assembly
Assembly-friendly

Proof

Tested in the igus lab:

A) Tensile strength test CFX clamps with stacker saddle
B) Comparison test of 3 different strain relief systems.

Conclusion: more than triple tensile strength of igus chainfix clamps
when compared with
conventional products

Chainfix clamps - mounted safely and even faster

Up to 15mm lower installation height than that of conventional clamps thanks to optimised housing height
Up to 3.5 times the force absorption of conventional clamps
Easy to read the part number and mark indicating the correct installation direction
Space and time-saving assembly
Improved base for easier fit into the C-profile
Simple assembly with threaded pins screwed with an Allen wrench
Durability for dynamic applications with improved stacker elements
Integrated ribs on the stacker elements prevent the cables from coming loose from the strain relief

Please note:

Ideally, cables should be fixed at both ends of the energy chain. In any case, they must be attached at the energy chain's moving end!
Using chainfix clamps on C-profiles in the mounting bracket for series 280, 2828, 290, 2928, R770, and R7728 requires a shortened bottom saddle. For shortened bottom saddles, add "K" to the part number. Example: Part No. CFX12.1K

Chainfix offers reduced installation height through set screw and optimal housing height

Overall height

If the energy chain glides over itself on long travels, screw heads on the strain relief element at the chain's fixed end must be at least 10mm from the top of the energy chain. As a result, many strain relief elements described here may be unsuitable for use at the fixed ends of long energy chains. Our clamps with threaded screws, developed specifically for low installation heights, have an installation height that is up to 15mm lower than that of conventional clamps. Strain relief elements can always be safely used for unsupported energy chains.
