e-skin® corrugated tube for cleanrooms
Safe and abrasion-resistant guidance of cables in cleanrooms
► Abrasion-resistant► IPA classification ISO class 1
► Compact and modular design
► Easy to open and flexible filling
► Resealable opening mechanism
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.
Product selection
The e-skin is a corrugated tube consisting of an upper and lower shell that form a complete enclosure when connected. The simple, resealable opening mechanism makes it easy to maintain and inspect cables the e-skin contains. The e-skin has many advantages over conventional corrugated tubes and is available in three different versions:e-skin SK | For unsupported lengths of up to 2.0m and installation space starting at 250mm

Adhesive dispenser for camera modules
Customer requirements: The company Mingseal manufactures products for the 3C industry (computer, communication and consumer electronics). The main product is an adhesive dispenser for camera modules. The igus E3 and E6 energy chain systems, which are already suitable for ISO class 1 according to IPA, were previously used as energy supply systems. Nowadays, however, the market demands an even higher particle-free standard (and thus theoretically an even better ISO class) than before, especially for mobile phone camera modules. The reason for this is the ever-increasing number of pixels on mobile phone cameras, because if there is just one particle on these modules, the entire module is abandoned and the overall equipment effectiveness (OEE) and the yield (YIELD) of the system drop enormously.
Our solutions: In the first step, the customer had to replace the energy chain with other products, e.g. welded cleanroom ribbon cables. The disadvantages of this solution soon became apparent: on the one hand, it was not possible to open the welded ribbon cables to add or replace cables, and on the other hand, the cables broke very quickly because they had to support themselves. After only half a year, the first defects appeared on these welded cables, which in turn led to the system coming to a standstill. The igus cleanroom energy supply system e-skin convinced the engineers at Mingseal. The unique openable corrugated tube for cleanrooms, which consists of an upper and lower shell, combined the engineers' openability, inherent rigidity, and compactness requirements with the highest cleanroom suitability according to ISO Class 1. The compact e-skin series SKS20 will be installed in new machines in the future.

Innovation
Corrugated e-skin tube is available in an enclosed version and a version with chambers that can be opened individually. This flexibility is an innovation and unique 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.
Why the e-skin corrugated tube?
1. Cleanroom ISO class 1.
Virtually no wear or abrasion
2. Two-piece corrugated tube.
Consisting of upper and lower shell
3. Circumferential mounting.
KMA mounting bracket, optionally with strain relief
4. Oval design
Prevents unintentional sideways movement
5. Fully enclosed.
Protection against dust and water ingress
6. Resealable opening mechanism.
Can be opened and closed like a zipper
7. Optional vertical separation.
Consisting of individual separators and full-width shelves
8. Minimisation of abrasion
With the new inner separation made of tribo-optimised iglidur material, the wear can be reduced by up to 80%.

Continuous test
The e-skin has been specially developed for cleanroom applications. In the laboratory, it withstood more than 6.4 million double strokes at 3m/s under realistic conditions.
Bending test
The standard bending tests show how flexible the e-skin soft e-skin soft is. It only bends, even under loads that would break other energy chains.
Noise level measurement
This test shows how quiet 'e-skin' corrugated tubes and 'e-skin flat' cleanroom cables are. Compared to competitors flat ribbon cables, the noise level of the e-skin flat is only 29dB(A).
