The ÖLFLEX® ROBUST 215 C 4X1 control cable from Lapp is a flexible, shielded cable designed for use in demanding environments. It is suitable for wiring internal machine and plant-wide control circuits and is specifically designed for areas where electromagnetic compatibility (EMC) is required. The cable is intended for fixed installation as well as occasional movement without tensile stress and can be used outdoors. Due to its robust construction and the use of high-quality insulating and sheathing materials made of TPE (Thermoplastic Elastomer), it is particularly weather-resistant and durable. Conductor identification is done by numbers, enabling secure assignment during wiring operations.

Applications

The cable is universally applicable in dry, wet, rough, and oily environments. Typical application areas include car washes, wastewater treatment plants, composting facilities, and applications in the food industry. It is also suitable for use under UV-C radiation, according to an internal test method by Lapp. The cable exhibits high resistance to water-soluble cleaning and cooling agents, is hot water and steam resistant, and can be used in frequent steam cleaning. It is also tested for use in fresh water up to a depth of 10 meters and a water temperature of 40 °C.

Functions and Features in Detail

A central feature of the ÖLFLEX® ROBUST 215 C 4X1 is the copper shielding braid with high coverage, providing effective protection against electromagnetic interference. The low-capacitance conductor insulation ensures minimal capacitance between conductors, which is advantageous for long transmission distances and helps maintain signal quality. The cable is rated for an operating voltage of U0/U: 300/500 V and features a flexible structure that allows use even at temperatures down to -40 °C. Its resistance to a wide range of chemicals, including ammonia compounds, biogas, and plant, animal, or synthetic fats and oils (e.g. bio-oils and ester-based hydraulic oils), makes it particularly suitable for industrial applications.

Technology Explained Simply

The use of TPE as insulating and sheathing material ensures high mechanical strength and chemical resistance. The copper shielding braid protects against electromagnetic interference, which is especially important in environments with strong electromagnetic fields. The low-capacitance insulation minimizes electrical capacitance between conductors, improving signal transmission over long cable runs. The flexible structure allows easy installation, even in tight bends, and the high temperature resistance extends the range of applications in climatically demanding environments.

Compatibility and Accessories

The cable is designed for use in industrial plants, particularly in areas with high requirements for chemical and mechanical resistance. It is suitable for connections in machine controls, plant automation, and process automation. Its use in conjunction with water-soluble cleaning and cooling agents, as well as in steam cleaning, is tested. The cable is not specifically designed for particular accessories, but it can be combined with standard cable glands, connectors, and other suitable connection elements, provided they meet the requirements of the respective application.

Installation and Mounting

The cable is designed for fixed installation and can be used for occasional movement without tensile stress. Its flexible structure facilitates installation, especially in tight bends. During installation, proper securing and avoidance of mechanical stress must be ensured. The use of appropriate cable glands or protective conduits is recommended, especially in environments with increased mechanical or chemical stress.

Operational Advantages

The ÖLFLEX® ROBUST 215 C 4X1 offers high protection against electromagnetic interference, enhancing signal quality in control and transmission systems. Its high chemical resistance and resilience against environmental influences such as moisture, oil, steam, and UV radiation ensure long service life and low maintenance requirements. The ability to operate in a wide temperature range from -40 °C to 40 °C in water enables flexible use in various industrial scenarios. The low-capacitance insulation supports signal transmission over long distances without significant attenuation.
