Applications
ÖLFLEX® 191 5G4 is suitable for applications in industrial automation, manufacturing technology, and the machine-building industry. It is frequently used in environments where oil-resistant cables are required, for example in metalworking, plastic processing, or packaging technology. The cable is intended for indoor use and can be operated in oily environments without significant degradation of electrical or mechanical properties.

Functions and Features in Detail
The cable features core identification by numbers, enabling simple and unambiguous assignment of individual cores. The construction is flexible to ensure easy installation and mounting. The enhanced oil resistance according to DIN EN 50363-4-1 (TM5) ensures longer service life in oily environments. The reduced wall thicknesses of the cable result in a space-saving design, which is advantageous when installing in tight spaces or complex machine constructions.

Technology Explained Simply
The control cable is rated for an operating voltage of U0/U: 300/500 V, making it suitable for use in typical industrial control and signal systems. The test voltage is 4000 V, ensuring high electrical safety and qualifying the cable for applications with increased safety requirements. The PVC insulation and PVC outer sheath provide sufficient mechanical and chemical resistance. The cable is UL recognized and carries UL/CSA certification, enabling use in the North American market.

Compatibility and Accessories
ÖLFLEX® 191 5G4 is designed as a multinorm cable and complies with multiple international standards, enabling universal use in various markets. The multiple certifications reduce part variety and support logistics processes. The cable is available in various conductor cross-sections up to 120 mm², with the type described here, 5G4 (5 cores, each 4 AWG), representing a specific configuration. Use with other products from the ÖLFLEX® range is possible, provided the respective technical requirements are met.

Installation and Mounting
The flexible construction of the cable facilitates installation, especially when routing in confined spaces or connecting components in complex machines. The cable is designed for fixed installation, with occasional movement without tensile stress permitted. Core identification by numbers supports correct wiring. Installation is typically carried out using suitable cable ties, protective conduits, or cable ducts, depending on environmental conditions and the requirements of the respective system.

Operational Advantages
ÖLFLEX® 191 5G4 offers high reliability in oily environments, extending maintenance intervals and reducing downtime. The multiple certifications enable flexible use in various markets, simplifying logistics processes. The space-saving design with reduced wall thicknesses allows for more efficient installation, especially in machines with limited space. The high electrical safety provided by the 4000 V test voltage ensures safe operation even under increased loads.
