e-skin® corrugated tube for cleanrooms

Guide cables in cleanrooms with e-skin® safely and abrasion-resistant

Corrugated e-skin® tube is available in an enclosed version and a version with chambers that can be opened individually. This flexibility is a unique innovation on the market so far. Furthermore, e-skin has sufficient inherent rigidity and a defined bend radius (55 to 100mm). The oval geometry ensures lateral stability. Short unsupported lengths are possible, even in small installation spaces. Conventional corrugated hoses do not offer this possibility. In addition, the energy supply is very quiet. Its noise level is only 29dB(A), 5dB(A) lower than that of conventional clean cables.


To keep rooms free from particles, all machine parts - the energy supplies too - have to be abrasion-resistant. With the e-skin® corrugated tube, systems are supplied with data, media and energy without unwanted particles contaminating the air.

e-skin® corrugated tubes are available in 3 versions:

e-skin® SK
For unsupported lengths up to 2m and installation space from 250mm

e-skin® soft SKS
For unsupported length up to 1.3m and installation space from 150mm

e-skin® Hybrid SKY
For unsupported length up to 1.4mm and installation space from 200mm
