The crossbars can easily be closed again by hand. By means of a screwdriver, this new generation allows the crossbars to be opened from the side of the chain link, which is advantageous in pre-assembled chains and areas with restricted access. Another constructive advancement on the E2.1 is the 'brake' on the stop dog of the chain links. This ensures a very quiet chain travel with lower vibration and noise. Compared to the previous generation the E2.1 is quieter by around 50 percent.

Design for maximum service life

The new E2.1 series has a very cable-friendly interior which adds more space for the same outer dimensions when compared to the E2/000. "For example, this can be an advantage in machine tools, because often very little space is available here," explains Harald Nehring, authorised officer for e-chain systems at igus. In keeping with the design of the interior of the chain igus provides separators with rounded edges for a long service life of hoses and cables. For a precise mounting of the separators an integrated grid system is provided on the crossbars. The new E2.1 has an interior height of 38 millimetres and an inner width of 65 millimetres. Other options and a version that snap's open along the inner radius will also be developed in the following months.
