Initiator cables, also referred to as sensor/actuator cables, connect control units and different sensors, or, in the case of reversal of the measurement principle, actuators. Frequently used abbreviations include ini or ini cable (plural: inis). Sensor or measurement transducers transform physical quantities such as rotation, speed, distance or length into analogue electric impulses. In the case of an actuator, the measured electric current (symbol: I, unit: ampere; A) or voltage (symbol: U, unit: volt; V) is transformed into temperature, pressure or torque. The connection cable consists of at least three cores with a small cross-section of between 0.14mm² and 0.34mm². In the simplest case, two cores are required for supplying the voltage, while the last core transmits an I/O signal. For sensitive applications, there are shielded versions in addition to the traditional ini cables to avoid EMC disruptions (electromagnetic compatibility).

Strain relief from igus® is specifically developed for use in e-chains® and dynamic applications. Thecombination of polymer strain relief components and chainflex® cable materials offers maximum holding force and very high service life for the cables. For a wide variety of applications, igus® offers the best solution with respect to cost and benefits; from the CFXL strain relief for long travels in harsh environments, or the new CFU honeycomb strain relief for fast assembly to the CFN chainfix nuggets for simple and inexpensive strain relief. igus® chainfix strain relief components have been successfully used in thousands of applications around the world for years.

chainflex® CF Air pneumatic hoses were tested in e-chains® for over several million bending cycles. Their outstanding features include flexibility, high abrasion resistance and very good resistance to oil and coolants. -For extremely heavy-duty applications -PU/PE hose -Oil- and coolant-resistant -Abrasion-resistant -Outside-toleranced -PVC and halogen-free

chainflex® robot cables are used in energy chains or 3D applications. The twistable robot cables meet extremely high industrial stress requirements and score points with properties such as resistance to hydrolysis and microbes, UV resistance and many, many others. Different types of robot cable are available, e.g. hybrid cables, fibre optic cables (FOCs), motor cables and servo cables. Typical application areas: - For heavy duty applications - Almost unlimited resistance to oil - Indoor and outdoor applications with average solar radiation - Unsupported travel distances and up to 100 m for gliding applications - Machining centres / machine tools, storage and retrieval systems, packaging industry, handling, refrigerating
