e-skin® soft cleanroom energy chains

With softer material, small installation height <200mm, flexible filling and can be shortened as necessary

  • Compact, modular design
  • Flexible filling
  • Reclosable opening mechanism: easy filling with "zipper" function
  • Especially suitable for cleanrooms
  • Can be shortened as necessary
  • KMA mounting bracket, optionally with strain relief
  • Mounting brackets to be sealed tightly by means of PU block
  • Quiet 32dBA

Typical application areas: cleanroom applications with compact installation spaces, short travels, semi-conductor production, LCD/LED panel production

Mounting brackets: strong, with integrated strain relief
Small installation space: small bend radii
Unsupported application due to stop-dogs on the upper shell of the e-skin
Cleanroom ISO Class 1: Virtually no wear or abrasion
Cable-friendly: defined minimum bend radius
Easy to assemble: Upper and lower shells can be opened for easy filling

Cleanroom classification IPA Class 1

Technical details

Commercially available corrugated hose

igus e-skin

Bend radius of corrugated hoses

Corrugated hoses have the same bend radius along their entire length

Upper/lower shell of e-skin

The e-skin consists of two shells (upper/lower shell). The shells can be configured in order to define the nature of the movement involved

Inherent rigidity of corrugated hoses

Corrugated hoses have little or no inherent rigidity.

Short unsupported e-skin lengths

e-skin is suitable for short unsupported lengths in a small installation space (2) and has a defined bend radius (5)

Lateral application of force

Very little if any stability in respect of forces acting on the sides

Lateral stability of the e-skin

Lateral stability thanks to the oval (6) geometry of the e-skin


Corrugated hoses cannot be used unsupported

e-skin for short unsupported lengths

e-skin supports itself and can be used for short, unsupported lengths


Corrugated hoses for dynamic applications cannot be opened

Outer radius of e-skin

e-skin can be opened on its outer radius and filled quickly

Interior of e-skin

The interior of corrugated tubes cannot be divided into sections

Interior separation of e-skin

e-skin can be fitted with interior separation system

Tested in the igus test laboratory for use in the real world

Continuous test

Continuous test

Developed for cleanroom applications, the e-skin has been tested under real conditions with 6.4 million double strokes at 3m/s in the laboratory.

Bending test

Bending test

The standard bending tests show how flexible the e-skin soft is. It only bends, even under loads that would break other energy chains.

Noise level measurement

Noise level measurement

This test shows how quiet 'e-skin' corrugated tubes and 'e-skin flat' cleanroom cables are. Compared to flat ribbon cables of competitors, the noise level of the e-skin flat is only 29dB(A).

Cables for cleanrooms

Suitable cables for cleanroom applications

  • 918 types with cleanroom classification IPA Class 1
  • 166 types with cleanroom classification IPA Class 2
  • With highly abrasion-resistant jacket materials
  • Tested and inspected with a 36 month guarantee
