Electrostatically conductive 3D energy chain

energy chains made of conductive ESD material are used to prevent static charges in the manufacturing processes of electronic components or assemblies. As early as 1992, igus® GmbH, together with the PTB (Physikalisch-Technische-Bundesanstalt) in Braunschweig, carried out measurements of the electrical surface leakage resistance for igus® energy chain with the special material igumid® GC, supplemented by further certifications in 1998 and 1999 according to DIN 53482 as well as the guideline on static electricity ZH1/200 of the Hauptverband der gewerblichen Berufsgenossenschaften.

Your advantages with ESD products

ESD material tested with over 10 million cycles for the highest requirements
Individual chain links can be replaced and it is not necessary to replace the entire system or dress pack
No waiting time, as sizes TRC.40, TRC.60 & TRC.70are available from stock in ESD design
Proven for years in use in explosion-proof areas

Design features of the igus® triflex® R series TRC e-chains®:

Approx. ±10° torsion per chain link
High tensile strength due to ball and socket joint
Option with fibre-rod for partial directional control and stiffening
No continuous support elements such as steel cable, spring elements or similar required
Wide range of accessories
Optional retraction systems guide the 3De chains® safely space-saving on the robot arm and reliably prevent loop formation
TRC - safe, closed, swarf-repellent
Smooth, robust outer contour to prevent snagging
High torsion resistance

Conductivity of igus®® products made from igumid® ESD

In contrast to temporarily applied conductive surface coatings or volatile incorporated antistatic agents, the additives used allow long-term, permanent and maintenance-free conductivity. To ensure conductivity, however, it is not enough for the individual components of an e-chain® to have conductivity; the entire e-chain® must have continuous conductivity from one end to the other. All products in this catalogue are optimised in this respect and the continuous conductivity is measured and documented by a 100% test before delivery.
Only e-chain® that have passed this test are subsequently labelled with the test seal and delivered. The colour of the triflex® R chains is a special feature, as they are not slate grey (≈RAL7015) but still black, similar to ≈RAL9004. Unfortunately, this makes it somewhat more difficult to distinguish them from standard materials. However, this is clearly defined by the material stamp.
