▊ FLEXMOV® Flexible cables

Flexible cables include control cables, data cables, bus cables,motor cables, robot cables, servo cables, measurement system cables, etc.

Control cables are common cables in the automation industry. High-frequency, long-term movements require control cables to maintain good wear resistance and mechanical properties in the cable chain.

Data cables Continuous movement within the cable chain requires extremely high EMC shielding requirements for cables, so the data cable needs to have special EMC protection requirements. In order to ensure that the data cable does not affect data transmission during the long-term bending movement of the cable chain, reliable structural design and The production process, especially the shielding layer.

Bus cables  The rapid development of Ethernet communications in the industrial field has placed extremely high requirements on the design and production of fieldbus cables. This is the only way to avoid mechanical damage to the cable during operation and signal loss during data transmission. Damage to the shielding layer and changes in characteristic wave impedance will increase the attenuation, which will lead to a sharp drop in the data transmission rate. Since the attenuation value will continue to change during the movement of the cable, troubleshooting becomes very difficult.

Robot cables used for torsional movements are subject to very specific stresses. In the case of shielded bus cables, the insulation and shielding are subject to high mechanical stress during bending and torsional movements.  This requires a completely different structural design concept for robot cables than for linear movements.

Servo cable  are standard accessories in drive technology and are commonly used in automation technology and mechanical structures. Due to the combination of power core wires and shielded pairs, the mechanical structure of the servo cable is always very unbalanced. In order to ensure that this asymmetry does not cause cable damage during operation in the drag chain, the servo cable must have a very special design, especially for long-distance gliding. As the speed of today's ICBT inverters continues to increase, low-capacitance insulating materials have become more important.

Motor cables are common accessories in drive technology and are used in automation technology and mechanical structures. As today's sports requirements are getting higher and higher, in order to ensure that power cables can operate safely and stably for millions of times, the cables need to have special conductors, insulation and core wire stranding designs. As the speed of today's IGBT inverters continues to increase, low-capacitance insulating materials have become crucial.

Measurement System Cables are important communication components connecting the drive and control systems. If there is no safe and timely feedback of electronic signals during movement, damage to the equipment may occur. Therefore, measurement system cables have special requirements for EMC protection. If there is continuous movement within the energy chain, the EMC shielding will be severely tested by mechanical stress. In order to ensure that these stresses do not cause failure of the measurement system, reliable structural design is very important, especially for shielding and stranded structures.
