The control cable YSLY-OZ 4X0,75 from Xaver Bechtold is a flexible cable designed for use in industrial automation, particularly in machine tools, conveyor and assembly lines, material handling systems, and general plant engineering. It is designed for fixed installation and flexible application, where the cable movement must occur without tensile stress and without forced guidance. The cable is designed for moderate mechanical stress and can be used in dry, damp, and wet rooms. The designation YSLY-OZ indicates a PVC control cable without an integrated protective conductor, with the cores being black and marked with a continuous digit print.

Applications
The cable is suitable for connecting control devices in production plants, where reliable signal transmission is required for both moving and fixed installations. It is frequently used in the manufacturing industry, connecting controls, sensors, actuators, and other electrical components. The operating conditions include both stationary and moving installations, with movement occurring without tensile load. The cable is suitable for indoor use, regardless of humidity, as long as there is no direct water exposure or aggressive chemicals in direct contact.

Functions and Equipment in Detail
The cable consists of fine-stranded, bare copper conductors according to VDE 0295 Class 5, ensuring high flexibility and durability under frequent movement. The cores are insulated with PVC and marked according to VDE 0293-308, with the designation OZ indicating the absence of a green-yellow protective core. The cores are stranded in layers, enabling even distribution of mechanical stress and minimal torsion during bending. The outer sheath is made of PVC and is grey in colour. The designation, dimensions, and VDE registration number are printed on the sheath, allowing easy identification and documentation.

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 quality test and demonstrates the insulation strength. The temperature range for moving applications is from -5 °C to +70 °C, and for fixed installation from -40 °C to +80 °C. This allows use in various environments, even with climatic fluctuations. 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 type B (equivalent to IEC 332-1), meaning the cable does not produce flames during a fire test and does not propagate flame beyond a specified area. The cable is largely resistant to acids, alkalis, and certain hydrocarbon compounds, making it suitable for industrial environments.

Compatibility and Accessories
The control cable YSLY-OZ 4X0,75 is suitable for use with standard connectors, cable lugs, and other electrical components designed for PVC insulation and copper conductors. The flexible construction allows easy processing and installation. Use in combination with other cables or in cable bundles is possible, provided mechanical and electrical requirements are met.

Installation and Mounting
Installation is carried out by routing in cable ducts, on trays, or in other suitable guiding systems. For flexible applications, the cable must move without tensile stress, and the specified bending radius must be observed. Connections are made using appropriate connectors or cable lugs designed for a cross-section of 0.75 mm². The cable can be installed indoors, provided environmental conditions remain within the specified temperature and humidity limits. Installation typically requires no additional protective measures, as the PVC insulation and sheath provide sufficient protection.

An operational advantage is the high mechanical stability during flexible use, enabling long service life and low maintenance frequency. Clear core identification simplifies installation and maintenance. Flame retardancy increases safety in electrical installations. Resistance to chemicals reduces the risk of insulation wear in industrial environments.
