RX e-tube enclosed cable carriers offer extreme protection against chips

The troubleshooter for energy supply systems in the chip area - available in 4 sizes. Chips and dirt can affect the service life of cables and hoses significantly. With the RX system, igus® offers an extremely tight, but yet very easy to open plastic e-tube.


  • Snap-open along the outer radius
  • A smooth, curved outer contour prevents chip buildup
  • Circumferential injection-moulded "sealing lips"
  • No holes, cracks, undercuts
  • Series RX40 is IP40 tested (TÜV Saarland)
  • Interior separation and guide trough available
  • Concealed pin/hole connection and stops
  • "RBR" version available with bending radius on both sides

Typical industry applications:  Machine tools, applications exposed to chips, dirt and dust, and general mechanical engineering

ESD classification: Electrically conductive ESD versions on request
UL94-V0 classification on request
e-tubes available as special design with HT material for 850°C hot chips

Submersion test in water - Various tube types were submerged under water. The new RX tube needs over 30 seconds until it is filled up, thus proving its high leak tightness
