triflex® R ESD | e-chains®

Enclosed type especially for robots and 3-dimensional applications

Energy chains made of conductive ESD material are used to avoid static charge in manufacturing processes for electronic components or assemblies. Measurements of the electrical surface leakage resistance for igus energy chains with the special material igumid GC, were made back in 1992 by igus GmbH together with the PTB (Physikalisch-Technische-Bundesanstalt) in Braunschweig, supplemented by additional certifications in 1998 and 1999 according to DIN 53482, and the guidelines for static electricity ZH1/200 of the Federation of Trade Associations.

1. TRC - enclosed chip-repellent design
High tensile strength absorption through the "ball and socket" joint
Multi-axis movement - twist up to ± 10° per chain link possible in longitudinal axis
Impact-resistant, robust, abrasion-resistant and dirt-repellent
Easy assembly and disassembly - single injection-moulded part
High stability - due to exterior stop-dogs
Electrically conductive: ESD versions
e-chains® colour: (according to RAL, approximate) black ≈ RAL9004
Small bend radii and short pitch
Easy attachment to the machine/robot

Technical design qualities of the igus® triflex® R TRC series of e-chains®:

approx. ±10° torsion per chain link

High tensile strength due to ball-and-socket joint

Fiber rod option for partial directional control and reinforcement

No support elements such as steel cables, springs etc. are necessary

Diverse range of accessories

Optional retraction systems reliably guide the 3D e-chains® along the robot arm and dependably prevent loop formation

TRC - Safe, enclosed, chip-repellent

Smooth and robust exterior against interfering edges

High torsion stability

Can be arbitrarily shortened or extended

Typical industries and applications

3 to 6 axes at robots

Multi-axis machine tools

Wet and cold cells

Painting applications and ESD

Sand and dust exposure

Linear motors

General mechanical engineering, etc.

Conductivity of igus® products from igumid ESD

In contrast to temporary conductive surface coatings or volatile incorporated antistatic agents, the additives used offer long lasting and maintenance-free conductivity. If individual e-chain components offer conductivity, this is not sufficient: the whole e-chain® from one end to the other must have continuous conductivity. All products in this catalogue are optimised in this regard and the continuous conductivity is measured and documented prior to delivery with 100% testing.
Only e-chains® that have passed this test are provided with the test seal and delivered. The colour of the triflex R chains is special because they are not slate grey (≈RAL7015) but still black, similar to ≈RAL9004. Unfortunately, this makes it somewhat more difficult to distinguish from standard materials. However, this is clearly defined via the material stamp.  

ESD test 100% of the produced ESD e-chains® are checked for their continuous conductivity from one end to the other
