The control cable YSLY-OZ 2X1.5 from Xaver Bechtold is a flexible control cable for use in industrial plant and machine construction technology. It is used to connect control devices on machine tools, conveyor and assembly lines, material handling systems, and in general plant engineering. The cable is designed for fixed installation as well as for flexible applications, where the cable moves freely without tensile stress and without forced guidance, subject to moderate mechanical stress. It is suitable for use in dry, damp, and wet rooms.

Applications
This control cable is used in industrial environments where reliable signal and control transmission is required. It is particularly suitable for installations requiring flexible cable movement, for example with movable tools, conveyor belts, or assembly equipment. The cable can also be used in rooms with increased humidity or occasional dampness, as it is resistant to moisture.

Functions and equipment in detail
The cable consists of bare, fine-stranded copper conductors in accordance with VDE 0295 Class 5, ensuring high flexibility and durability. The conductors are insulated with PVC and feature numbered identification in accordance with VDE 0293-308. In the YSLY-OZ variant, it is a version without a protective conductor; the conductors are black and marked with a continuous digit print. The conductors are stranded in layers, ensuring even distribution of mechanical stress. The outer sheath is made of PVC and is grey in colour. The designation, dimensions, and VDE registration number are printed on the sheath.

Technology explained simply
The rated voltage is 300/500 V, meaning the cable is designed for alternating voltages up to 500 V and direct voltages up to 300 V. The test voltage of 4000 V serves safety testing and indicates the electrical strength of the insulation. The temperature resistance is -5 °C to +70 °C for moving applications and -40 °C to +80 °C for fixed installation. The bending radius is 4 times the cable diameter for fixed installation and 15 times for flexible use, defining the mechanical load capacity. Flame retardancy corresponds to VDE 0472 Part 804, Test Method B (equivalent to IEC 332-1), ensuring limited flame spread in case of fire. The cable is largely resistant to chemicals such as acids, alkalis, and certain hydrocarbon compounds, making it suitable for industrial environments.

Compatibility and accessories
The control cable YSLY-OZ is designed for use with control devices, switchgear, and other electrical components in plant engineering. It can be combined with other control cables of type YSLY-JZ (with protective conductor) depending on the requirements for the protective conductor.

Installation and mounting
Mounting is carried out by fixed installation or flexible arrangement, with bending radii to be observed. For flexible use, a bending radius of at least 15 times the cable diameter must be maintained to avoid mechanical damage. The cable must not be installed under tensile stress. Installation is carried out in dry, damp, or wet rooms, with ambient temperature within the specified limits.

Advantages in operation
The control cable YSLY-OZ offers high mechanical and chemical resistance, ensuring long service life and reliable performance in industrial applications. The numbered identification of the conductors simplifies installation and maintenance. The PVC insulation and sheathing provide good electrical insulation and flame retardancy. The flexible structure allows use in moving machine parts without damaging the cable.
