The control cable YSLY-JB 4X0.75 from Xaver Bechtold is a flexible connection and wiring cable for control devices in industrial applications. It is used in areas such as machine tools, conveyor and assembly lines, material handling systems, and general plant engineering. The cable is designed for both fixed installation and flexible use, with movements occurring without tensile stress and without forced guidance. It is suitable for use in dry, damp, and wet rooms, provided that medium mechanical stresses are present.

Flexible control cable with copper conductors according to VDE 0295 class 5, which are bare and fine-stranded, ensures high flexibility and long service life. The conductors are insulated with PVC and colour-coded according to VDE 0293-308. The designation JB indicates that the cable contains coloured conductors as well as a green-yellow protective conductor. The conductors are stranded in layers, which enables even distribution of mechanical stress and a stable cable structure. The outer sheath is made of PVC in grey colour and protects the internal conductors from external influences.

Application areas include industrial automation systems, where reliable signal transmission between control devices and drives is required. The cable is particularly suitable for installations where cable movement occurs without tensile stress, for example in assembly systems or with movable machine parts. The operating conditions range from dry indoor environments to wet environments, as long as the mechanical stress remains medium.

Technology explained simply: The rated voltage is 300/500 V, which is sufficient for most industrial control applications. The test voltage of 4000 V ensures electrical insulation under high voltage stress. The temperature range is -5 °C to +70 °C for flexible use and -40 °C to +80 °C for fixed installation. This allows use in environments with varying climatic conditions, including cool production halls or warm operating rooms. The bending radius is 4 times the cable diameter for fixed installation and 15 times for flexible use, which facilitates installation and cable movement. Flame retardancy according to VDE 0472 part 804, test method B (equivalent to IEC 332-1), ensures sufficient fire behaviour tolerance.

Compatibility and accessories: The control cable is suitable for use with standard connectors, cable lugs, and other connection elements in industrial applications. The colour coding of the conductors according to VDE 0293-308 enables clear identification and simplifies installation. The cable is largely resistant to the effects of chemicals such as acids, alkalis, and certain hydrocarbon compounds, making it suitable for environments with low chemical stress.

Installation and mounting: The cable can be installed in fixed installations or for flexible use. For flexible use, it is important to ensure that no tensile stress occurs and that the movement guidance remains free. The bending radii are larger for flexible use to minimise mechanical stress. The grey PVC sheath provides protection against mechanical influences and environmental conditions.

Operational advantages: The combination of flexible structure, chemical resistance, and electrical reliability ensures long service life and low maintenance. The clear identification of conductors reduces errors during installation. The cable is designed for use in industrial environments with medium mechanical and chemical stresses, making it a reliable solution in many applications.
