Structure of the servo cable The cores of the cables are made of strands made of very bend-resistant bare copper wires. The core insulation consists of a mechanically high-quality and particularly low-capacity TPE mixture. The overall shield forms a braid of tinned copper wires, constructed with an optimised braid angle designed for movement. This ensures long-term bending movements for long-term electromagnetic compatibility protection. Depending on the material, the outer jacket is resistant to UV light, chemicals, friction and very high or very low temperatures. Depending on the conditions of use, either the iguPUR developed by igus® or the common materials PUR (polyurethane), PVC (polyvinyl chloride) or TPE (thermoplastic elastomer) are used as material for the outer jacket . Finding the right material is facilitated by the filter function "Requirements", which allows you to select the conditions of your intended use.
The cores are arranged around a high tensile strength centre element and are held in the intended position with a gusset-filling inner jacket. This structure guarantees the long service life of chainflex® servo cables, which can be up to several million double strokes. For the determination of the expected service life under the specific operating conditions, the user has access to the online service life calculator.
The servo cables are sold by the metre by igus® GmbH. If required, harnessed cables with connectors are also supplied according to customer specifications.
