The control cable ÖLFLEX® CLASSIC 110 21G0,5 from Lapp is a flexible PVC control cable for use in industrial plants and machines. It features 21 conductors with a cross-section of 0.5 mm² and is designed for an operating voltage of 300/500 V. The cable is suitable for medium mechanical stress and can be flexibly used at temperatures down to -15 °C. It is intended for fixed installation and allows occasional movement without tensile stress. The cable construction also permits permanent, moving use in moving machine parts as well as in drag chains. The PVC insulation and outer sheath are resistant to acids and alkalis and are suitable for use in dry and damp rooms. The cable is universally applicable for wiring internal machine and plant-wide control circuits. Due to its special construction, it is also suitable for torsion applications in wind turbines.

Applications
ÖLFLEX CLASSIC 110 21G0,5 is designed for applications in industry, particularly in machine and plant engineering. It is suitable for wiring control and signal circuits in production plants, conveyor technology, packaging machines, and in energy technology, for example in wind turbines. The cable is suitable for use in dry and damp environments and features high mechanical strength, enabling use under medium stress conditions. The flexible structure allows use in moving components, such as in drag chains or rotating parts.

Functions and Equipment in Detail
The cable features numbered conductor identification, which simplifies assignment and wiring during operation. The PVC outer sheath is oil-resistant according to DIN EN 50290-2-22 (TM54) and provides protection against aggressive chemicals. The tested resistance to ECOLAB® disinfectants and cleaning agents makes the cable suitable for applications in the food industry or in the medical technology sector. The VDE registration number 7030 confirms tested quality and safety. The cable is available in standard lengths, with the specified length here being 500 meters.

Technology Explained Simply
The control cable is designed for an operating voltage of 300/500 V, making it suitable for most industrial control and signal applications. The test voltage of 4000 V ensures high electrical safety. The reduced wall thickness of the outer sheath enables a space-saving construction, which offers advantages in limited installation cross-sections. The cable is flexible and can be used for occasional movements without tensile stress. The PVC insulation provides sufficient protection against moisture and chemical influences.

Compatibility and Accessories
ÖLFLEX CLASSIC 110 21G0,5 is part of a comprehensive product family with 145 standard items, covering 2 to 100 conductors in various cross-sections and lengths. The cable is suitable for use with standard cable lugs, connectors, and other connection elements designed for PVC insulation. The classification of fire behavior according to EU Directive 305/2011 (BauPVO/CPR) enables use in installations that must comply with the Construction Products Regulation requirements. The exact article number selection for fire behavior classification is available on the LAPP website.

Installation and Mounting
The cable is intended for fixed installation and can be used for occasional movements without tensile stress. The flexible structure allows easy installation in confined spaces and complex routing geometries. The numbered conductor identification simplifies installation and subsequent maintenance. The cable can be installed in drag chains and moving machine parts, provided mechanical stress remains within the specified limits. Installation is typically done without additional tools, although the use of cable cutters and strippers is recommended to ensure clean processing.

Operational Advantages
ÖLFLEX CLASSIC 110 21G0,5 offers high reliability and longevity in industrial applications. The oil-resistant PVC insulation protects the conductors from wear caused by oils and fats, extending the cable’s service life. The tested resistance to disinfectants and cleaning agents reduces the risk of material damage in hygienically demanding environments. The flexible structure and reduced wall thickness enable compact installation, which is advantageous in limited space conditions. The VDE-tested quality and fire behavior classification according to BauPVO/CPR increase safety and facilitate compliance verification during plant commissioning.
