The control cable YSLY-JZ 4X1,0 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 and flexible application, and can be used with free movement without tensile stress and without forced movement guidance under 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 transmission between control and drive components is required. It is particularly suitable for installations requiring flexible cable movement, such as in assembly systems or with movable machine tools. The cable features a green-yellow protective conductor, making it suitable for use in electrically protected installations. Use in wet rooms is possible due to the PVC insulation and sheath, although the cable is not intended for permanent underwater application.

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 under frequent movement. The conductors are insulated with PVC and marked in accordance with VDE 0293-308. The designation JZ indicates that the conductors are black and marked with a continuous numerical print, including a green-yellow protective conductor. The conductors are stranded in layers, enabling even distribution of mechanical stress and improved flexibility. The sheath is made of PVC, grey in colour, with a print indicating the designation, dimensions, and VDE registration number.

Technology Explained Simply
The rated voltage is 300/500 V, indicating the maximum voltage the cable can safely transmit. The test voltage of 4000 V serves as a safety test to verify insulation strength. The temperature ranges are specified as -5 °C to +70 °C for moving applications and -40 °C to +80 °C for fixed installation. This means the cable can be used in environments with temperatures from -5 °C when in motion, while fixed installation allows operation down to -40 °C. The bending radius is 4 times the cable diameter for fixed installation and 15 times for flexible application, defining the mechanical load capacity. Flame retardancy corresponds to VDE 0472 Part 804, Test Method B (equivalent to IEC 332-1), meaning the cable must not drip burning material and must not propagate flame during a fire test. The cable is largely resistant to chemicals such as acids, alkalis, and certain hydrocarbon compounds, making it suitable for industrial environments with chemical exposure.

Compatibility and Accessories
The control cable YSLY-JZ 4X1,0 is compatible with standard connectors and cable glands designed for PVC insulation. It can be combined with other control cables of the YSLY type, particularly in installations requiring uniform cabling technology. The JZ marking allows easy identification of the conductors, which is advantageous during installation and maintenance. The cable is available in ring form with a length of 100 metres, enabling flexible installation in larger systems.

Installation and Mounting
Installation is carried out by routing in suitable ducts or cable channels. For flexible applications, it is essential to ensure that the bending radii are not exceeded to guarantee cable lifespan. The cable must not be installed under tensile stress, as this may cause premature ageing or conductor breakage. Connections between conductors are made using suitable connectors or soldering, with the insulation treated in accordance with VDE regulations. The green-yellow protective conductor must be connected in accordance with VDE 0100-550.

Operational Advantages
The control cable offers high mechanical and thermal load capacity, making it suitable for industrial environments. The PVC insulation and sheath provide good chemical resistance and protection against moisture. The flexible construction with fine-stranded copper conductors enables long service life under moving conditions. Clear conductor marking simplifies installation and maintenance. Flame retardancy in accordance with VDE 0472 Part 804, Test Method B, enhances operational safety, especially in enclosed spaces or areas with increased fire risk.
