The ÖLFLEX® FD 855 P 7G1,5 control cable from Lapp is a highly flexible, continuously moving cable designed for use in moving machine parts and in drag chains. It features a PUR outer sheath that is mechanically robust and chemically resistant, particularly insensitive to mineral oil-based lubricants. The cable is suitable for outdoor use and can be employed in dry, damp, rough, and oily environments. The cable construction enables flexible, continuously moving operation at temperatures down to -40 °C. UL certification allows use in North America, with an operating voltage of 1000 V permitted according to UL. The PUR outer sheath is abrasion-resistant, crack-resistant, and cut-resistant, increasing the cable’s service life in demanding environments. The LAPP performance class 'Extended Line' ensures long-term use in drag chains, especially in applications with long travel distances or high accelerations.

Flexible control cable for continuously moving applications is enabled by a highly flexible construction and a particularly short conductor stranding, which allows for minimal bending radii. The low-capacitance conductor insulation ensures minimal signal distortion and is particularly advantageous for long transmission paths. The low particle emission during continuous movement reduces contamination in sensitive systems. Conductor identification is done by numbers, enabling easy assignment and wiring.

Application areas include industrial applications with moving machine parts, such as in manufacturing automation, robotics, or the packaging industry. The cable is particularly suitable for drag chains, where high mechanical loads and frequent movements occur. The PUR outer sheath protects the cable from mechanical stress and chemical influences, increasing reliability in demanding environments.

Technology explained simply shows that the PUR sheath is not only mechanically robust but also chemically resistant, making it suitable for oily and aggressive environments. High flexibility is achieved through the special cable construction, which enables continuous movement without material fatigue. UL certification is an important requirement for use in North America, where specific safety standards apply.

Compatibility and accessories include use in systems requiring high mechanical load capacity and chemical resistance. The cable is designed for use in drag chains and can be combined with other components designed for moving applications. UL certification enables use in North American facilities, with the operating voltage of 1000 V according to UL to be considered.

Installation and mounting are carried out considering the minimal bending radii enabled by the short conductor stranding. The cable can be installed in moving machine parts and drag chains, where the mechanical durability and chemical resistance of the PUR sheath increase service life. Conductor identification by numbers simplifies wiring and maintenance.

Operational advantages include high service life, low particle emission, and reliability in demanding environments. The cable is designed for continuous movement and offers high mechanical and chemical resistance. UL certification expands the application range into the North American market, with the operating voltage of 1000 V according to UL to be considered. The low-capacitance conductor insulation ensures clear signal transmission over long distances.
